My ex completely gaslighted me Infront of ppl today

Unfortunately he’s my bd. I wish I didn’t have to see or speak to him but he’s my baby’s dad!!!! He pretends to act like he’s still not begging me for another baby or beg me to have sex Bc the girl he’s seeing was around. He called me a liar and everything like wth it was just so stressful. I had a stressful day just needed to vent. Cause like why apologize to me to still be doing the same fuckery all he does is lieeeeee I can’t take it anymore. I try to be calm and talk nice to avoid conflict but when he gets caught up in his actions I get upset now I look like I’m the crazy one. I freaking hate this guy I don’t wanna deal with this shit this year but that’s my baby dadddd smh idk what to do man.

Stress is not even the worddddd my therapist been out for a whole month I’m going through it. I just want to break down and cry
