I've always been like this. I used to never be that big into dating. I rather flirt than date. But anyway my first love lasted for 2 years, though it was emotionally draining and affected my life big time. Since then I've been emotionally confused with my feelings. I think I love someone but really don't. Don't love someone then think I do and get back with them, later just to find out I really don't.
I blame my ADD on the reason I get bored with men so fast. I've had some really nice guys which have lasted a few months but I started to feel bored and suffocated so I'd breakup with them and move on.
It seems the more I get older the faster I'm getting bored.
I can't seem to last a few days now.
I'm in a relationship right now. We had a rough start but it's going good now and we're hitting that month mark. I was sure that I really liked him but while talking to him, it suddenly hit me that I don't love or really like him more than a friend. I'm bored with him. I try avoiding him. I kind of developed feelings for another person which is a lost cause... I think that I'm in love with that other person... considering they make me cry easily and emotionally frustrated. I spend more time talking to them then my actual boyfriend. But It's the same situation as the 2 yr guy... so I try to distance myself but they easily draw me in.
It's not excitement that I'm looking for. I really don't care about that. I want to be with someone but at the same time I don't. I never want to get married. I'm starting to get bored with relationships all together not just the guys I date.
I'm positive I've been in real love at least 3 times.
2 yr guy.
Run away guy (chased him and when I finally got him he stayed for a few months. It was great. I was sure he was the one, never got bored but then he ran away. Came back but I refused to go back to him because I was hurt.)
And this new person who is my best friends.

I like the idea of saying 'I have someone'. But actually having someone is what annoys me. So why don't I like relationships? Why do I get bored easily? And why do I put more effort in the 'impossible' ones rather than the ones I can have? Am I always going to be like this? What the heck is wrong with me?  

There is nothing wrong with you, it just sounds to me you just haven't found the right guy yet. If this doesn't seem right to you then maybe there is a conflict you went through in the past that made you behave the way you do towards men..
