My Obsessive Boyfriend

Hi! I've been in a relationship for a year. Everything was going perfectly, but he started to get more obsessive. I have a group of friends (only girls) and we go out regularly, we know each other from a handful of ladies and we're super close. yes, we were dating until he started making trouble with me. Now I see them rarely, and every time we go out he keeps texting me where I am, he wants me to write to him when I'm going somewhere and when I get there, and every minute he wants me to be on the phone. I try to explain to him that I rarely see them and can't just sit on my phone, but he doesn't want to understand. The last time we left, one of them' boyfriends called to see if they could see each other in a hurry because he's going to the country. We went to see them. My boyfriend started "you were just girls," "you're lying to me again," and so on. He knows he's both walking. And every time I go out, he's going to find something to give me trouble and ruin my mood, and in the end, I just stay out and look stupid, because I know that later when we go out, he's going to have to fight me and make me feel guilty and that because of me and my friends, our relationship was going to break down. But the problem isn't just there. makes me trouble what I wear. I don't dress. He's making me even a problem with jeans, they're tight. I'd be lying at home in comfortable clothes all day. That's why if I go out, I'm most comfortable putting on leggings in a hurry, because it's looser, and my jeans tighten and cause me even more pain. He doesn't understand it and calls me a whore because I wanted others to look at me. He tells me it's all because he's concerned, but I think it's pure jealousy and mistrust. He's the one who cheated on past relationships, not me. Sometimes it me off and I just want to stay, but I can't. I'm too attached, and I always think it's going to go away, but not. Tell me, am I exaggerating?
