Hello all, I'm looking for some insight and hopefully some reassurance.

I'm about to get into a custody battle with my sons mom the baby mama (bm) I'm retired and have been raising my son full time for the past year and a half. I've kept a log book on all the nights he's stayed with me, with the bm, and all his doctors appointments I've taken him to. Looking at my log book, my son has spent about 95% of his time with me. I also have texts from her stating that my son prefers to be with me over her, etc. My bm does onlyfans, and I recently discovered she's meeting up with her "fans" to have sex in exchange for money, basically prostituting herself. (Which I don't why, she has a full time job and she's been getting 500 in child support from me)

With this being said, how does my outcome look for winning this battle? Anybody else have any similar experiences? Thanks.

Edit: I'm in Texas and I do have screen shots of her setting up a date/time/place/money to meet with someone
