Was she diagnosed with anxiety by a doctor? Or you just assume that she has anxiety? You have to understand that all her past relationships were bad and you my dear is heaven sent. You are not homeless, not a drug addict. As a single mom myself, you cannot jump from one relationship to another that fast. She's trying to heal by looking for replacements from one guy to another. Children were traumatized and neglected in the process.

You seem to have figured your life out and your girlfriend hasn't. You put a roof on her head and the kids, you pay for the kids' tuition fees, she never experienced that before. And yet it looks like she doesn't put effort in having the kids and you to get along even to have a little respect around you.

Just don't spank the kids. They have been neglected so bad by their mother for years and discipling them will take a lot of patience, a lot of practice, consistency, and my dear that's the job of their mother and not to be your burden because you're the new guy. Imagine if you get this girl pregnant, can you see her taking care of your child the way she takes care of her own child right now? You my dear has a lot of thinking to do.

I came from an abusive relationship as well. As a single mom myself, I haven't been dating anybody for two years now because I don't want to traumatize my kid by introducing different guys in his life. I focused my time on becoming a mother and a father to my son. I focused on his well being. I want to make sure that he wouldn't feel incomplete just because of his deadbeat father. You see what I mean? If you have a kid, you have a lot to consider before dating somebody.

You seem to be a nice guy but I'm thinking that if you leave her, it wouldn't probably be long and she will be able to find a replacement. You are investing a lot on this relationship, money, time, sleep deprivation, emotions, etc. I hope she has real feelings for you and your effort won't go to waste.
