I'm 21 and have been with my partner for 5 years. We're getting married next July and usually everything's great but recently he's been coming home from work (army) barely talking to me, going up to bed hours earlier then usual and is always asleep when I go up and every time we talk we end up rowing. He's going away for a month on Monday and I really wanted to make this time with him special but he just doesn't seem interested in me. Usually he is the most loving, sensitive person in the world and the opposite of me who isn't very slushy or romantic. I keep asking him about it and he tells me to shut up in a jokey way but then whenever I try and hug him he seems to quickly pull away and says he's busy and needs to do something. Its starting to make me really insecure. I cant talk to anyone about it as everyone is full steam ahead with the wedding details and don't want to worry anyone incase i'm just being silly. We got through his 6 month deployment and me going of to uni so don't know why things are suddenly going so wrong! I'm at a loss is it just something that happens when you've been living together for a while? so confused I'm at breaking point!!!!
I wonder if he's having big doubts about the marriage. Make him feel safe to sit down and discuss them with you, and see if that is the case. Another thing you might want to consider is the possibly that he has cheated during the time you were apart, leading to this kind of withdrawn behavior.
In any case, you want to make sure you're getting married happily, with your mind clear and your heart ready - and know the other person feels the same way.
hope this helps. - <3
