Marriage help

my husband has a few problems and has lost a few ppl he loved before meeting me including his father. he has never really opened up and let me in and never been able to let himself love me. he treats the children the same way and has had a lot of affairs because he says it is easier to deal with flings where no feelings are involved. we have both had enough of this and even if just for the childrens sake i want to help him. please if you could advise us in anyway we would be very grateful

First off, you saying you are all staying together because of the kid is not a good idea. Staying together is not the same as being married happily. What parents often forget is that they need to show their kids a happy loving relationship. It is a prime example and the kids will base it off of for the rest of their lives. If they see two people stuck together and not happy, at a young age they'll believe that this is the way it's supposed to be. In my opinion you Guys might as well separate and find another happy relationship that will be good for your kids and yourself. Also don't stay with someone who cheats on you. You're only hurting yourself
