My friend has just dumped her long-term boyfriend because of her relationship with God. I don't know what to think?

A friend of mine I fell for after I split with my ex of 5 years has just become single. She finished with her boyfriend of 3 & years a few weeks ago and told me about it this evening. She always claimed she wasn't good enough for him and often worried that he would leave her for someone better, but told me tonight that it was in fact her who finished with him?

Basically, she thinks too much. She is 21 and worries about the future more than anything. It's a constant thought and destroys her.

She told me this evening that she finished with him because her faith has become more apparent than ever and feels that as he isn't a believer, that the future will be difficult as she will not be able to share her faith with him. She absolutely adored him and has now let him go over God.

It's a hard stance as a friend to sit back and accept this has happened. I am a firm believer that God and religion is man made. This however doesn't mean that I don't 100% respect religion and believers (obviously not extremists.)

My Mum and Grandma are both Christians and are probably the two nicest people on Earth that I know in person. The fact that their faith keeps them going and makes them tremendous people is fantastic, I would NEVER take that away from them over my personal opinions. I respect them way too much, as I do her.

But it's hard to sit back and swallow...as a friend, that she has finished with her boyfriend over God, because in my eyes she has finished with him over nothing as I don't believe. Yet she claims that - though life is extremely difficult right now because she misses him, she feels she can never be with an atheist ever again and that she finally feels at peace with herself and that God is watching over her. She used to have counseling weekly due to how much she beats herself up mentally, so to hear her say this is a massive improvement.

But again, as an atheist I am both bothered because she has finished with him over nothing - yet she is in a happier place.

Confusing.

Anyway, apologies for rambling, this is my first ever post on Reddit after being simply a reader for a long time.

Anyone care to throw in their two cents or have you ever been in a similar position?

TL;DR - Friend finishes with boyfriend over God. It has helped her mentally become strong. As an atheist friend, I find it hard to accept, but have to respect her decision.
