I hooked up with my ex’s mom

We broke up a few months ago and it wasn’t the best split in the world. So much so that she has been talking bad about me online and to mutual friends etc. I haven’t responded and have kept the details of our relationship very much to myself.

I met her mom out at the club this past weekend and she came up to me and I expected to have an argument on my hands but she was really apologetic and said that she was sad to see us broken up, that I was the best thing that ever happened to her daughter.

The conversation got a bit flirty when she said if she was younger she’d snatch me up for herself and so I called her bluff. One thing led to another and we were back at my place and we hooked up.

I don’t know whether to feel guilty about it or not tbh.
