🙃help!

I been dealing with this guy for what will make 2 years in March on the 28th (my birthday) I love him and it’s obvious that he loves me considering all the risks he takes by even being with me due to the age difference . Going in the the relationship I was told that he had two children from the same woman and their relationship was completely over . A couple months ago when he and I was arguing he told me that they were having another baby 😔.i decided to move on I gave this nice guy I met my number and we began to talk , so my ex got a new number and text me from it I answer the message thinking it was the new guy long story short he didn’t like the idea of me moving on and on the inside neither did I we decided to try to make things work but how can we when he always bring up the other guy and the fact that I hurt him he doesn’t understand that he’s hurt me more than anything by having this baby the two do even compare 🤷🏽‍♀️🤦🏽‍♀️
