"Moving in"

So me and my fiance had a wonderful baby boy i love both of them to death. and we live with our parents and its been time for us to move in. She says its time to be a family and she is right and i can understand her anger and madness i didnt move us in to our on place. I been wanting to my self.

But now here comes the problem. let me start by first saying i have my problems. i act like a baby sometimes. and i also a little rough. not the gentlest guy. i get mad easy i been trying to control that doing well laterly. but still needs improvement. also i a little attached lets not lie more attached do to my past with my family so qhen im around her its like i can not be under her or all over her. its a flaw i have i know.

Now to the issuse laterly she has been doing things that make me not want to move in yet. She use to talk to a male friend behind my back. i found out and i let it go cause i cant tell her not to have friends but why hide it was my problem.then this same male friend and her was flirt. she says its not flirt u be the judge. first she says i want u to go with me on my trip out of town. then he sends a kiss face and says laugh. now she is engaged at this time. also he ask for pictures and then says i wont tell no one what u send me. he is also marry then he ask her to come his job she says she knows where is it but when i ask she dont know now. really. then come to find out they was gonna meet in the park to "check under her hood of her car" really really. the same car i took to sears and found out what was wrong it. what is he gonna find at the park that the car repair company didnt. and she knows where the paper is to see whats wrong with it. i didnt know until i read the messages but she say she was gonna tell me. please rise your hand if u believe that shit. then months before we get in a fight she comes on this very site and talks about how much she miss her first. and now she talking about moving like this is not on my mind. to me if u didnt catch this she would be doing this in our house or worst have the guy at the house while im working. and the day she was talking to him i was work 15 house a double shift she says she was to busy to text back. i see why now

Am i wrong for holding up on moving in?
