I'm going to break up with my boyfriend because he's christian
Is religion a big issue in your relationship?
I would clash with him over religious arguments.
If religious beliefs are that important to you, then it can compromise a relationship. Constant arguments are not healthy for a relationship.
We will always argue about religion and I want to enjoy being single for a change
I understand how you feel. It would be grating to see each other and be arguing so much all of the time. It is good you recognized that it was going nowhere and it needed to end.
