Hi sweetie, so sorry for the reason you are here, but you are in a good place.
Just some quick tips: The weekends are very quiet. Stick to one thread so we can keep up with your situation. Post to others so we get to know you.
Most of us here have heard some variation of the things your h has said to you. I am not an expert, but many of them sound like MLC.
You've done some very good things already. I know what you mean about the GAL. My family was my whole life. But, you know what, that's not really healthy. In order for us to be complete, we need to find what makes us happy and that can't come from other people.
So, right now the focus needs to be on you and your son. Try to think of some things you always wanted to try, maybe join a club, check out the library - they have different groups. Or you mentioned having a few more pounds you want to lose. Start walking or join a gym.
It's time to do some soul searching, too. Figure out the things about yourself that you want to change. Then go abut trying to change them. The changes have to be for you though, otherwise they won't stick.
Others will be along to give you some insight and get you started on some reading.
Remember, you are not alone. We are here for you.
Keep doing what you're doing. No relationship talks, work on you.
It's all a process.One step at a time. There are no quick fixes, but, if you walk the journey, you will come out stronger on the other side.
