<human>: I started casually dating my lover for the last few months. We used to have a serious relationship but broke up. I didn't want to be with him again, because I didn't feel like I am ready to be in a relationship. I also didn't want to become serious with him again, because of the past. I didn't want to start something only to have it end.

Another reason that I didn't want to get serious with him is because we have some major differences. I am a religious girl of a certain faith, and he is from an entirely different faith. Sometimes he does things that are considered sins in my religion. This is a problem for me. I don't want to love someone if he does things that I don't agree with or can not do with him. I feel like I may end up engaging in the same behaviors just because I am with him. 

I don't know what to do about this. I know you can not force someone to change, especially when it comes to something like religion. But my religion is very important to me, and I can't compromise on it.

That is why I am so unsure about pursuing a deeper relationship with him. In my mind once you become serious with someone, then there is no going back. That is why I want to be very careful about the person I am dating. 

And on one hand, he is very caring, considerate of me. He also tries to make me smile, and make me feel good. I do the same for him. I like him as a person, I think he would be a good partner. 

However, his lifestyle is an issue for me. I don't like some of the thing that he does. He drink a lot of alcohol. Also, he went to a festival where everything they ate there is not allowed in my religion. I have brought this up to him, and he said he will try to be better. But I am not sure what he will do. 

My question is what should I do? Should I follow my heart, and be with someone I am falling in love with? Or should I slow the relationship down and become less serious about him?

Can you provide a brief rundown of the text in within 3 sentences?
