I'm tired of such a life

I'm 29 years old, my husband 32. There are 2 children. The older child is not from him. He does not work. Also does not try to search. Neither does it help at home or with children. He drinks with friends almost every day. Promises have bored him, which he does not fulfill. Tired of lugging one family.

There is one man who is waiting for me, he made a proposal. Lives in another city. I have feelings for this person too. My husband's already burned out. So I do not know what to do? Children then love their father. Can, that will advise. Thank you for attention. All good and peace.
