My (22f) boyfriend (25m) wears my clothes and I don't like it

I've been with my boyfriend for 5 years and we live together. I've always been okay with sharing clothes and I borrowed a lot of his stuff in the past. I always asked first and never touched anything that he didn't want me to borrow. I've never ruined his clothes or stained them. I always returned them as soon as I was done with it and I never touched his clothes if I was going to drink or smoke in them.<br><br>I've never asked to borrow any of his clothes in the past year. I've started to get uncomfortable with him wearing my clothes. <br><br>At first it was okay when he would borrow my sweatshirt because it was too big and I thought it was cute. He would wear it in the house to sit around but didn't go outside with it. <br><br>As time went on he started to wear it outside in front of his friends. His friends never mentioned it but I was embarrassed. I told him that I didn't like it because it made me feel self-conscious. He said I shouldn't be embarrassed of it because he likes wearing it and it's comfortable. He agreed to only wear it in the house but would still do it against my will when I was busy or away. <br><br>He started to take my clothes without asking and I would have to hunt for it. I found my clothes, that I don't want him to borrow, in his bed, on his side of the hanger, in his hamper, etc. I have to constantly search for my clothes to make sure he doesn't have it. <br><br>I have confronted him multiple times about how I don't like it. He wears all of my clothes and I don't want him to. Before I didn't care, but when I started to want nicer clothes, he doesn't like it because he wears them. I have to consider if he will like that item of clothing if I buy it. He has ruined some of my clothes and I don't give a shit about fashion anymore because I don't want to give him an excuse to wear my clothes. <br><br>He would wear my clothes but also put his name on them. He would write, "Property of (his name)" on the shirt. That's embarrassing and it makes me mad that I don't have a say in what clothes I buy now. <br><br>I've had to throw out clothes because he doesn't listen to me. I don't want my clothes to go to waste and I'll donate it but I don't want him to have it. If I throw it out, he doesn't know where it is because we both throw out our garbage. I've done this to some of the clothes he took. I have also cut the sleeves into oblivion so he can't wear it. <br><br>Every time I confront him, he says he'll stop but never does. He says how much he loves my clothes and he doesn't see the problem with wearing them. He also doesn't see the problem with lying about it.<br><br>I'm so tired of this and I want to get his attention. I want him to see how uncomfortable it makes me. I wanted to go into his closet and ruin all of it. I want to ruin all his clothes but I know that will just lead to a massive fight and it's against my better judgement. I just want him to see how I feel.
