Interfaith relationship

My boyfriend and I had been together for 3 years. At the beginning of the relationship I was 18 and I had strayed away from Islam a bit and I regret it. However, I fell deeply in love with him. I don’t see myself with anyone else, but I know I cannot be with him. I’m ready to get back on my deen and begin practicing Islam again, but he is not Muslim and he has recently revealed to me that he does not intend on converting. That is completely okay, I would never try to force or guilt trip anybody into changing their religion. That is something that should be decided on their own and they have faith in it. Now, I am aware that dating in Islam is haram and I take full responsibility so please haram police do not attack me. I recently had to call things off with him because we are 21 years old and I feel like if we continue this we will just be wasting eachothers times since marriage can not happen for us because Interfaith marriage for muslim women is forbidden. I feel like a terrible person and he told me that he doesn’t think I love him because I allowed my parents request for me to be married to a Muslim man to overpower our relationship. Yes, my parents had a part of me calling the relationship off but I truly just want to get closer to my religion and I don’t think I will be able to do that if I continue sinning by being with him. I also thought about our future, if we were to have kids they would be so confused about their religion. I would want them to be Muslim and practice Islam but he has already stated that he would want them to practice Christian practices such as celebrating Christmas and doing things he enjoyed as a child from his Christian background. I don’t know how to go about this because we are so close and this is heartbreaking.
