My heart hurts so much ☹️

My daughters father & I were together for 5 years & broke up 7 months ago. He moved on pretty quickly & well… I still haven’t. I’ve hung out with a few guys but I just haven’t felt it 🥺 anyways he lives next door to the girl he’s messing around with & even tho I know he isn’t loyal to her he definitely shows her more respect then he’s shown me which hurts a lot. When I go by to pick up child support he won’t come to my window he’ll go to my passenger side and hand me the money if he comes somewhere with me he’ll sit in the back seat.. I’m hurting so bad rn. He barely did that stuff for me after 5 years but does it for her to me.. idk I’m having a hard time even tho I know I will never get back with him after all this.. as much as I try moving on I have no interest right now for any guy and I feel kind of pathetic and I feel like I look pathetic to him. I cried today after he gave me the child support and was gonna text him but stopped myself. I feel like she won.
