Nees help with my relationship

Sorry for the long post. Hopefully at least one of you takes the time to read it. My bf and i met 2 years ago. We’re in our early 20’s and at the beginning everything was awesome. I was honestly the happiest girl ever. He was so romantic, always checking up on me, always making time for me. Then i got pregnant. We decided to move in together well because it was time already.. At the beginning of my pregnancy everything was still good. Then in the last months. We were more distant with eachother. He avoided me and we would never have sex because he said he was “ afraid of hurting the baby” i totally understood him. Then when i gave birth. 1 month later i found very inappropriate things on his phone. Like nude pictures of “models” and girls on his social media. That was a hard moment for me because i couldn’t take such disrespect. I eventually kicked him out but my mom talked to me and told me to think about our daughter. She was only 1 month old and needed both her parents. He begged me to forgive him. That he was going to change and blah blah. So i decided to forgive him having my daughter in mind. Some days we’re good. We get along and what not. But he works in construction so he’s always “tired” we never go out.. We NEVER have sex. Sometimes i have to beg him. And all he tells me is that he is tired that we will “another day” I have cried on many occasions because i think that i am not good enough for him. That he’s avoiding me in every possible way. Sometimes max we have sex is 2 times a month. but it seems like he just doesn’t care. Now, he decided to get a second job on the weekends 🥺 so now i know for sure that he won’t make any time for his daughter and me.. This situation just makes me sad. I asked him why he needed a second job and he said to make more money and i asked him if he cared more about his money than spending time with us. Our baby will grow up and its time and moments that you can’t get back. Like i said i have talked to him about both situations but he usually puts my feelings to the side. What should i do. i start working tuesday. so i was planning to save up and probably just get my own place. I know por relationship is not working anymore and i wish he would put the same effort that i am putting.
