Guys are confusing

Why is it when you tell a guy you like them and then admit you love them they come up with some lame ass excuse to run and hide and say they need a break? A break from what exactly may I ask? Mind you this guy I am interested in he has had some past relationships bite him in the ass so many times and the girls he's gotten with have lied to him, cheated on him and other things too. I tell him I'm not like the rest but in his eyes I am. Then he tells me he likes me a lot but doesn't do anything to show it. He definitely isn't with his feelings like some men are unfortunately. He tells me he doesn't have control over me because I'm not with him, he doesn't care what I do but when I decided I hooked up with my ex and a guy friend he flipped his lid and of course pins it all on me. Telling me my behavior isn't going to change. That's why he hasn't asked me out. I'm a liar basically he won't ever trust me and other things. Calls me names like a slut or a whore. I mean if you like someone yeah be honest with them but don't call them names to get your point across. I decided that a week ago him and I should just be friends because I can see nothing was going to come of us and what's the point in waiting for someone who isn't ever going to trust me. I was honest with him though about having sex with my ex and a guy friend shouldn't he accept that as something? Plus I've never lied to him but he thinks anything that comes out a womans mouth is lies. I have hid things from him but then told him what they were. Then he tells me it's okay I understand you just wanted one thing mind you we've been talking for 4 months and we've had sex like maybe 20 times. When we stopped having sex I could have stopped talking to him but didn't because sex wasn't all that I wanted. I just don't get guys. I decided to work things out with my ex. Hey he's the only MAN that loves me for me, will do anything for me and has been there for me. So I realized what I needed back. Hopefully him and I can work things out and stay strong forever.
