I bore him girls; he’s now leaving us

I’m 32, a mother of three girls and have been married for nine years. We were a happy family until last year when I discovered that my husband was having an affair with a young woman in our estate. We fought about it and he assured me that it was over. She disappeared for a while and now she is back with a baby boy and this has driven him crazy. He spends all his time at her place only to come home past 11pm. She has told me to my face that my time with him is almost over because I failed to give him what he wanted the most. She said that it is only a matter of time and I think she is right. I think I’m losing the man I love and I don’t know what I can do to keep him. I don’t mind him supporting them, but I just hope that we can remain his first priority. Please advice.
