(43M) and my (30F) partner been together for 11 years unmarried, and we have a 7 year old daughter. On April 29th, 2025 My partner told me she is a lesbian and broke up with me right there. I was so blindsided by this, I never saw any signs of this coming.

We both do not make enough money for either one of us to move out, and I really wanted to try to stay at least as friends and as roommates for our daughters sake. Not even a week later while I was in so much pain and in hell, my partner found a new person on a discord LBGTQA.

She mention that she was just looking for friends and that was all that it was. Fast forward a few days and she started going out all night with this person after work. Ignoring our daughters and mines request to come home to help our daughter go to sleep. This person and her were now friends with benefits and were in some kind of poly relationship.

This continue for awhile, causing more suffering and problems for our daughter and I, she kept lying about when she would be at home. One morning I came across something in the our bathroom and ask my partner about it and she told me the person she was seeing was a Trans Woman with their male parts still there. I consider myself an Ally, but this really really hurt me a lot.

As this continue my partner started spending less time and focus on our daughter and I, and more lying. She became so cold and mean towards me that I couldn't handle it anymore. We got into a big fight and she moved out.

Has anyone had a former partner personally change so much after coming out?
