So .. Here's the deal.
Ive been with my bf for 5 months now, he's the total opposite of me. I told him in the very first days we dated that I was not really sure if I was ready to start a new relationship because my last two ended up really bad. But he was always very nice and caring and he always told me not to worry. I never totally believed him, simply cuz I don't trust men.
For several times I broke up with him - Once because his x came around his house with her kid and they all went to mcdonalds. And he told me that he was gonna stay at home cuz he wasnt feelin that well. I passed by his house, pure coincidence, and I saw them all headin to mcdonalds all happy n sh*t .. I was like " Hell no."
Broke up.
We eventually got back together and he said that he did it for the kid [ which isnt his ] and he was gon tell me [ all em bullshits ]
Second time - He was actin up - All confident, taking me for granted - Not answering my text messages, barely talked to me and whenever he did, didnt sound the same. Blamed it on the work - Cuz he worked way too much and was really tired, this and that.
I said " Brotha - You worked before you met me, when you met, and all this while... And you never act this way . So it has to be something else. "
Broke up, came back again. He changed, treated me real good and all the stuff we ladies like.
Now he's coming back to what made me break up the second time. And right now Im like - Is this just a phase? Or ...
You know . I swear I feel like breaking up, but at the same time I wonder if there's anything that's actually affecting him, that right now he can't give me all the attention and love that he use to. I tried talking to him, but all he says is that he can't talk about it right now. Which makes me wanna go back to the first option - BreakUp.
Cuz I know something is up.

What you guys think ?

And oh - if there's any typo, sorry, dont mind . [ im not english ]
