Marriage is hard work especially if you and your spouse are at odds, and trying to raise a family at that. I would like to commend you on staying in you're marriage and trying to work it out. You are not alone in this battle myself included. I don't know how strong your faith is but the thing that had helped me and that is working is prayer. I was very close to a divorce a year ago and I ask God to help me fix it and he did. Now it didn't happen overnight but it did change and my husband is not the same man he was a year ago. Most of all it made things in my home livable and peaceful. There's also a book called the power of a praying wife that is awesome. I hope everything work's out for you and you're family.
Its more hard to leave because its became a routine your used to it you get used to seeing someone every day and being with them let alone imaging it with someone else and having a xhild its hard to leave
Sounds like my life in a nutshell i want to leave somedays and when i get to the point if leaving he acts completely different like the old him. I dont want to raise a child without a father i know that if i leave my child wont see much if any of its father. But you have to remember to look out for yourself and that little one if dad wants to be part of YOUR family he will get his butt in gear and make an effort. If its healthier for you to leave than leave but if you heart is in the relationship and there is a chance try one last time. Don't waste all your energy on it though your gonna need all the energy and strength you can get.
