My common-law wife lives with me only for money

I've been living with my common-law wife for two years now. She has a little one.daughter who started calling me dad.

Everything was fine, but for half a year now it's as if she's been replaced. She doesn't love me anyway, she said so right away, but some secrets started,communication with someone on the Internet and then insults of the lowest degree began for any reason, showing me the door, etc. I myself love her very much, but I can’t leave. She once told me: “if you want, live, if you want, leave, when I come back from work everything is fine for three days, and then it all starts again. The exmy wife gives me her son for good, that is, she refuses him and because of thisthe relationship with my common-law wife got even worse, how did she find out about this. How can I overcome myself, take and leave calmly and without scandals?

I think about her all the time, she's not the same in bed as before, she always finds different excuses, every time I think that I'll come and then definitely leave, but for some reason it doesn't work out when I arrive. And test-antibiotic.com friends say that it's not your thing, that everything between you is based only on money and nothing more. Yes, I myself understand that I'm simply missing out on mylife , I'm wasting my time, although I myselfa five year old son is growing up. Maybe it's worth living for your son, than living with a person who doesn't need you and who lives with you only for the money.
