Confused need advice bad

Me and my gf have been together for a year and 4 months now and live together. 4 months ago she said I was drinking to often and had lost interest so I quit drinking I love her. Things got back to normal till about 2 months ago. She started getting distant and will not have sex no matter how romantic I get.stop doing things with me but goes out with her cousin every weekend.I asked her why and she said her cousin don't like me so I asked why don't we go do stuff just me and you sometime. She said idk and left to her cousins.then last weekend she said she thinks she should be single and is confused in her head cause she don't want to hurt me and it's not fair to me...but didn't want to break up just needed to think things through to make sure it's not just a phase before she made a rarash decision.and left with her cousin and stayed gone the whole weekend and ignored the 3 text I sent her. We talked again when she got back and told her I didn't appreciate the way she treated me she said sorry but wanted to think about things so I said ok I'll respect that..then this week all of a sudden it's like I'm a stranger she speaks in a monotone voice to me short responses still kisses me and says I love you only if I say it first. She text me at her break every morning morning babe love you and calls me on lunch but this week she cut lunch call short 3 days in a row and yesterday didn't call at all I asked if there is another man and she got mad and said I'm not having this conversation I didn't accuse just asked...so I looked at our phone messege history online and there is a number she has been texting all day everyday and called the days she cut our call short and the day she didn't call...it could just be a friend but idk I haven't told her about it...I'm confused is she really trying to sort things out or is she stringing me along to make it easier to leave why not just break up with me I'd be fine if I just knew any advise would be helpful thank you

I don't know who's name the apartment is in but if it's in hers pay what you owe and move out. If it's in yours tell her to pack it up and say goodbye . Something happened in your relationship no telling what. I know it's hard but break up and move on but that's what it looks like you're going to have to do. You'll find someone who really loves you out there. Believe me you'll find another girlfriend they're out there

Look at her actions and forget about her words. If she genuinely loved you, and she was talking to a friend the times that she's been 'missing', she would be reassuring you that all's well in your relationship together, by using actions. Instead her behavior tells you the exact opposite and hence your confusion. Your post is about your gut instinct starting to kick in..listen to it and let it guide you.
