Ok i need advice or to vent.

Im 23, My daughter is almost 2, i am a single Mother this has been the most hardest thing for me, me and her dad aren’t together never wore. It was a one night stand. but we share her sometimes. I hate him so much. And the pain he has givin me has tore me apart. My point is has anyone else felt like giving up Not wanting to be a mother anymore? I dont want to share a kid with that asshole. And she reminds so much of him. I feel guilt i feel like the worse person for feeling this way. But i am SO not motivated to be. A mom. I have her 24/7 7 days of the week. He maybe picks her once on the weekend and that’s sometimes, while hes out having the time of his life having a love life wich i cannot get because im to busy raising our daughter. Whenever i tell him i hate him he tells me im bipolar or something rude or calls me a child. and he gets ppl on his side like im the bad one. no one understands mothers get ppd and i feel i did, and so much anxiety. I just want to runaway sometimes.🥺🥺😪😟 i feel like i fucked up my life by getting pregnant by him, and i don’t want to say that because i love my daughter and she makes me happy. But sometimes, i just feel the sadness like a wave sometimes. Were i want to say i give up on bieng a mom, here you raise her im done, i want to runaway sometimes But i can’t.
