This girl keeps messaging me?

So me and my ex have been dating on and off for 4 years I love this girl and I know she loves me. Every-time I try to end it she gets upset because of the religion differences she told me she can make it work and I can’t just seen how it will work. With different cultures and religion but she said she will make it work. This girl has been there for me throughout everything..

yesterday I tried to end it I told her I was busy she rang me so many times wanting to see me one more time before we end things I was so angry because I told her I was busy and she kept on trying still. When I got to see her she was telling me how much she loves me and she will make it work because nothing is easy in life you have to work for it. She told me I haven’t there for her much but her love for me has made her stay. I do agree I haven’t been there for her as much since her mother was diagnosed with cancer but she still stayed with me. She used to ring me all the time saying why do you not call me or message me truth it I’ve just been in my head about this whole situation regarding the religion differences. I do love her with my whole heart and I don’t even need to question her love for me. I just don’t know what to do in this situation we are currently not together and I know I won't across another woman like her. Can anyone help me out
