I've stopped talking to some of my girlfriends because I feel they are judging me
I'm sure they mean well, looking out for you.
Try to keep the relationship with them positive as well, if you know you can handle your H set some boundaries with your friends about how you want the relationship with them to be.
Having someone to rely on is invaluable. They too can get burnt out when they see they're "not getting through to you", as in, get you to give up the relationship. Its a "what did he do this time... " for them moment and I guess you're noticing it as judging.
I'm finding it harder to respect myself for staying with him
Figuring out why you feel this way is a good first step. Staying in a relationship is not bad in itself, but if you feel bad about it there's probably a reason deep down.
Search what is it about staying firm in your decision to stay is colliding with your values that you feel like you're not living up to them, losing respect for yourself.
Others can provide some insight as well so feel free to share and ask questions, often all it takes is a change in perspective to start moving in the right direction.
