Should I end my relationship?

In the little over a year we’ve been together we’ve went through a lot. We got pregnant last year but lost our baby girl four months before she was due. We had only been together nine months at that point. Two weeks before she was born I was put on bed rest and had to leave work. When that happened I got evicted from my apartment and my son and I moved into my boyfriend’s house. Tensions were already high as we prepared the loss of our child and struggled with our relationship because of it. While our daughter was in the hospital I found out my boyfriend had been texting, receiving and sending explicit pictures to a girl and that had been going on for four months. I forgave him as it didn’t feel right to leave while we both lost a child. In January he borrowed my car while I had a girls night with friends and a month later I found out he had girls over at the house and somehow doesn’t remember taking a photo of one of the girls with her top off in our room. He couldn’t truthfully tell me if he used my car to pick them or if they came over there on their own. And tonight while he was asleep I went through his phone and found yet again, another girl he had been texting, sending and receiving explicit pictures from and was also paying her for them. But this time telling her he’s ready to leave me for her, begging her to delete the messages and blaming it on him being drunk. Still have no idea if he actually hooked up with any of these women. I packed my things and left for the night. But my question is, can I forgive this? Is it worth starting my life over from the ground up? He keeps saying I never loved him and he didn’t cheat and that I’m just looking for the easy way out
