Bf went back to his wife but told me he misses and loves me still... he went back for his kids and said he has to try one last time ... should I wait for him?

I know how hard this will be to hear, but don't wait for him. If he doesn't stay with you, then you weren't his first choice. and No one deserves that pain. Now I won't tell you what to do, but I hope that you get out of that situation. I went through this with an ex of mine. I waited for him. I waited for a year but it wasn't the best thing to do. People like that are toxic and will only hurt you. That is emotional blackmail. Him telling you he still loves you, is him hoping to keep you trapped, entangled is his web. You are better than that.

I think you should communicate with him about how you feel. Honestly though, it doesn't seem like he knows how he feels himself. Love needs to be both ways, if he doesn't care about you, it's not worth waiting for him. Relationships aren't without sacrifice, so maybe you can workout how he can be there with his kids while being with you. He should have done that before starting his relationship with you, though. And make sure you are okay with him including his kids. He is their father, after all. Remember though, you need to be sure of your feelings first.
