You're not wrong. Leave as soon as you can. Big hugs, and stay strong, momma. You're doing what's best for your kids. That's not the sort of person who is going to be a good example for them.
No, you are not wrong at all. It sounds like you are ready to make things all about your kids (well you have been in that mind frame for a very long time now), and he is not. It's okay to still be a parent and have a good time (whether with or without alcohol), as long as you are still setting a good example for your children. Would he one day want his son to smoke weed like he does or need it like he does, I am sure he doesn't want that.... and that is just the mind frame he needs to be in, that everything he does is the #1 example to his son. Right now all you need is support and a loving/nurturing environment for your children, if you are not getting that where you are at then it's time to move on... like you said. I think you are making a very wise decision. It's not to say there isn't hope in the future for your sons father to change or make things right, but for now he is not making you and the kids his #1 priority. So, do what you have to do and go from there. Good luck and stay strong :)
You definitely need get out and be around people that are going to promote a healthy and supportive environment for you and your kids. It's great that you're concerned for your kids and are already thinking of getting them out. I'm sure it'll be hard at first, but remember it is so worth it!
Your not wrong you need to do whats best for your kids. Kids dont need to grow up around drugs and alcohol. Its far better to move back with your family cause sounds like he doesn't want to change. Some people are just completely set in their ways and dont want to change no matter what. Your kids need a better environment and if that better environment is with your family than thats where you should be. Really you just have to do whats in your heart and best for your kids.
I think you're doing the right thing. I'm in a similar situation with my husband, but it's not so much drugs and alcohol as him being lazy, won't work and we fight all the time. I also think he is too hard and mean to my oldest (not his) which I've mentioned he needs to lighten up but he doesn't listen. I told him last night that I didn't want to be with him anymore, and we are working on getting him out of the house. Not only do I not want this kind of relationship for me because I think I deserve something better, but I don't want my kids to grow up thinking this kind of relationship is normal. I want my son to grow up to be the kind of man that knows how to love and support his family and i want my daughter to find a man like that. It's up to us as parents to influence how our children grow up, and the best way they learn is by example. So be the example you want your children to see. It's going to be hard for you, but I know you are strong enough to do what is right for you and your kids.
I'm kinda going through the same thing but i'm married. We have argued for months and i was going to leave but decided not to b/c we have been together since i was 13, i'm now 27. He has been controling for a long time now and i got so tried of it that i told him i was going to leave and he really didn't care. I have asked him to help and he gets mad and gets mad at everything i do. When i decided to stay he said that he was going to do anything he wants to and i can't say a damn thing about it and that i can do anything too but nope it's not. He can do anything and i can't. I thought it was going to change but it didn't. He ccomplained all the time and complained about not getting any and didn't understand why. I was the one doing everything, getting up 2-3 times a night while he slept. I can't stand to do anything now even sex. I get frustrated and i just don't like it anymore. He doesn't show me love and thinks he shouldn't have to. I don't feel like i have a husband anymore but a roommate with some(not a lot) benefits. I still can do stuff by myself, i have to go with my mom or him. I can't have friends over or at least come in the house but his but can come over EVERYDAY but he doesn't come in b/c(accord to my husband) he doesn't want to be around me. Now i feel stuck and unloved.
I'm sorry for my rant but i just wanted to show you that you are not alone with having to deal with a little boy who thinks he is a man. And i get what your saying about the weed(not going into that). So be strong, leave and stand up for what you want.
I've been through the same. There are support groups out there!! Try Al-anon or Nar-anon. There are e-meetings too!
