I am heavily seeking advice in my relationship. Especially from Christians whom have dated nonbelievers

I (23F) am currently in a relatively fresh relationship. I am a Christian, he is not at all. We stand far apart politically and religiously, and going into it I made the choice to put that aside. So far it has not caused any communication problems between us. We are both open minded and understanding which is a reason why I like him so much. Although I foresee it most likely being difficult to have him agree with my views regardless if he is willing to listen.

When I had ended my previous relationship of multiple years, a big reason I did not hesitate to leave a good guy was due to him not being much of a Christian. It was easy for me to end it as well as move on quickly for that reason alone. I was convinced for the next couple years to follow that I would rather be independent, lacking all desires for a potential husband, also lacking lust.

Versus: This past year I had met a new guy, turned out I really liked him even though he is almost the opposite of what I’d expect to want out of a man. I have almost no complaints about him. He is such a genuine sweetheart in every way. The problem I am having is more within myself. In the past I found it very easy to part ways with someone who had no intent to have a relationship under God. This time on the other hand I walked into this current relationship knowing well that he is far from being Christian and despite this, I still can’t convince myself that I should move on for the better if that doesn’t change. Usually any other time it is very easy for me to detach. For the first time in a long time I have had lustful urges, and caved into them. This also feels problematic within myself and my decisions.

As a person he is far from problematic and would be willing to listen if I wanted to speak about my Christianity. Although I am not optimistic he would convert. The issue is that I feel like this relationship causes me to ignore God a bit sometimes, versus a year ago I THOUGHT I was fully willing to stay single forever and be closer to God instead. Suddenly I’m attached to this new guy and cannot imagine walking away.

Not asking for the advice to be anything in particular. Any sort of feedback is great. Whatever feels right to say after absorbing this information.
