Confused over relationship break

Hi this is going to be a long story so apologies, I am 29 and my gf is 33 we have been together for 7years and have a 2yr old little boy together, we have always had a pretty good relationship and hardly ever argued. For the past 6months or so my gf has all of a sudden desired the need of a new social life she has started going to the local pub, which I understand she needs time to her self sometimes, the problem is she doesn't come back until 3or4am the next day and this behaviour seem to me to be very excessive. She has also made new friends some of which are men which I am not happy about as I am quite old fashioned and she is constantly on her phone she has also gotten in to the habit of drinkin approx 2bottles of wine nearly every night when she is at home. This behaviour has lead to many problems mainly me being worried abt her, I don't worry abt her cheating as she is very loyal. At times it feels like I am dealing with a rebellious teenager, when I try and confront her abt there things she says she is going throught some changes and not to worry. I feel she has been a bit selfish in her behaviour and although I understand her need for some self time I would prefer her to be a bit more consideriate of me ie comein home at a reasonable time. I try to be understanding but her attitude seems to be, this is what I am doing and that's it. As a result we have been argueing and snapping at each other , we had a massive arguement when she went to a hen party and left at 6pm. Sat evening and came back at 1530pm Sunday afternoon! She could not understand what the issue was with this considering we have a child together as a result of this arguement she decided we need a break. I was devastated as I really do love her and thought that was the end. We had a couple of days with no contact and then we talked she explained she did not want to break up for good, we are still together but she stil needs space. In our time apart I did some soul searching and realised that I may have been unreasonable at times so I apologised to her and am willing to make changes so we can continue being together. I am confused about this as she says she needs to be able to trust me again and she will cuddle me but will not kiss me as she says it's too soon, I don't understand this I thought the reason for the break was to realise where we were going wrong, she says it's one thing saying these things to her but I need to prove it to her? Any advice?

7 year changes affect us all. It can be the beginning of something new or the end of something old...or both. Her actions speak of someone looking for something else in her life at the moment. Alcohol is also damaging your relationship and is damaging her health if her consumption is what you state it is. It will also affect her decisions about everything including your relationship together and the well being of your son. Never mind her left field behavior, two bottles of wine a night IS excessive and if she's drinking at home, then that alone should scare you. If she is loyal, then ask yourself just how loyal is she? No contact for two days should tell you that you are not her priority(at the moment)plus the fact that after you have voiced a very reasonable query of your relationship together, she has argued with you. If she can't understand your alarm at her absence from you and your son for nearly 24 hours, then she has acknowledged that while her son is safe with you,(trust)she is free to do what she wants when she wants. This is extremely selfish but she won't see it that way at the moment. Yes, everybody goes through changes but not everybody 'discards' their partners when they do. You don't need to apologise to her for her actions and don't change a thing about yourself. Stay true to your old fashioned values. I'm sorry, it's easy to say, but this will either go two ways but you can't do anything about her present decisions and actions but you can stay strong for the sake of your son.

Hi thankyou for your replies, she does not pass out just says she gets caught up in enjoying herself. Like I said before when I try and speak with her about these problems it gets her back up and her mentality is very much , if you tell me to do something il do the opposite just for the sake of it, which is why I say she acts like a rebellious teenager. I feel like I have tried with her but she is only interested in what she wants at moment , I have apologised to her as I feel I probably could have been a bit more understanding at times. I feel at the moment that I have tried to 'put my foot down 'as you say but it does not seem to have got me anywhere, as she seems to automatically go in the opposite direction no matter how delicate I am about it, so now I am trying the opposite approach for the sake of our son as I would rather be at home with him then away from him , in the hope that this is a phase that she is going through and will be over sooner rather than later.
