How can I get my boyfriend to be like he was before jail?

ok well me and ma b/f have been together 4 almost 5months and we been through a lot he was in jail like a month ago and he got out like the past week he has been actin diff and I dont know why he been actin stuck up and not talkin to me or payin as much attention to me as usual my question is what can I do to get him bac to the way he was before

saying hes gay isnt going to help...well I think form personal experiences that the whole experiecne of being in jail made him feel different...wheny uo go to jail you have to be tougher especially edpending on what kind of jail yuo go to ...but dont worry sooner or later he'll come around

shoot you probly can't, because he's probly gay..
