Am i cut out for this?

I've been thinking a lot lately. I don't think of myself as bad, or anything like that. I like to think i'm a good friend and a good girlfriend. But now, i keep getting my boyfriend mad. I feel like everything i do is just ticking him off. He's the jealous type, and i honestly don't mind that. I'd call myself the jealous type too, so him being concerned doesn't phase me. It shows me he cares, but then it makes me think he doesnt trust me? I don't do much for him to get jealous about, but he still finds those little things he can bring up to cause a fight. I don't understand, does he like fighting? I know i don't. I grew up around a lot of fighting, and yelling in my house. That's not something i'm looking for in my relationship. I don't want my relationship to be a repeat of my upbringing. I love Dylan so much. I don't mind that he gets jealous. But lately he's been getting mad because of my tumblr and the things i reblog.. I've been on that website for at least two years now, and i never thought it would ever be such a problem. He keeps finding ways to get pissed because of it, and he makes me look like a bad guy. I might just be an asshole but i don't see what the big deal is. I feel like hes blowing it way out of proportion, its just a website! Its just an animated screen with pictures and shit on it. I don't understand the big deal! I almost feel trapped. I thought i could manage him being concerned and wanting me not to do stuff, but now its just everything! Everything i do is wrong! That might be an exaggeration, but that's what it feels like. I've had that feeling my whole life i don't want that in my relationship. Everything i do, he has a problem with. I try to make it so i'm a good girlfriend and he doesn't have to get mad at me, but i just can't. He always find something he doesn't like. & When he does, it just makes me think more and more that he doesn't really want me. If he doesn't like anything about me, then how can he love me? I'm really interested in Photography, i'm currently in a photography class and i really like it. I would tell him what i learned about, or what my projects are. Then he'll just tell me how dumb it is, he hates the idea of it, but i love it. That's something i'm really passionate about and he just shoots me down, i don't think he realizes that hurts me. I mean its not the biggest deal but i don't know it just really upsets me. I don't talk to him about photography anymore..  I'm only saying the bad things about him now though. Yeah he can be a bit controlling with his jealously and he may not trust me but there are many things that i love about him. For instants, he has inspired me to change a lot, I'm a better person since we've been going out. Now that i have a boyfriend, i always want him to be proud I've been exercising more, and trying to keep my grades up. I also stopped smoking, which he hates. He made me realize that its nasty and that i honestly am not interested in it at all. Its just unhealthy, and i'm smart enough to realize i don't need to hurt my body to feel better. I don't feel the need to do it anymore either. I used to just have so much stressed and i felt trapped i needed an escape, and smoking was the escape. It worked i guessed but i knew it wasn't right, i had so many nightmares about that. It was a bad habit and i never should of started it. I didn't need it, i'm strong enough to deal with things on my own instead of just trying to run away from them. But now those problems feel like nothing. He makes me so happy, just having someone i know cares, and is there for me makes all the difference. I love being around him, he just makes everything better. Not only is he my boyfriend but hes my best friend i can tell him anything. I'm comfortable around him, and we laugh and joke and its just perfect. He has an amazing sense of humor, that's something i really love about him. He always makes jokes and always knows how to make me laugh. He can joke around but he also knows when to stop and be serious. He's sweet and caring and always there for me. I just always want to be with him. I love him i really do. And i want us to last. I want him and the jealousy, controlling, corcky, joking, lovable things he does. I find him perfect. & that's where i'm leaving it.
