I have one son I was 42 when he was born. There is nothing my wife could do to get me to leave Him. Don’t get me wrong I love her as well. He is more important than her. If parents both put there kids best intrest above there own crap like what your dealing with wouldn’t happen. Your in this because she put her selfish intrests above her childrens. To me there is a special place in hell for those type of people. You have kids . Your intrests are second to them. Your moral responsibility is do every thing you do in there best intrest. Again if you feel you were betrayed. She betrayed your kids even worse. To upset there family strength, there safety security. Was way worse than your trust, Your responsibility here is not fixing her. Its to your kids. Her responsibilty is to fix her self. She may do that. The trust you once had. Will never be the same don’t kid your self, That doesn’t mean you can’t get past it if she truly changes. Just means her choices have changed your relationship for ever. It possibly could be good. But never the same. Full trust not possible. The doubt will always rise again. Even if it never happens again. My point is if your a father poor all you love and effort into your kids. I say that as a 55yo man that had a absent father . That had very negitive effects that lasted until my 30s . Drugs drinking not letting anyone close to me. Studys show you the father . Matter more . If your a loving father involved daily in there lifes as children. Do not let her ever push you out. Hope that helps. You want love, your kids are full of that for you. Go get it DAD!!!!!
