Because she got bored and isn't a real Christian. She doesn't want to get close to Jesus, she should be already doing that before you met her! Honestly. Please just listen. She wants to be in this world, she is carnal minded. There is nothing wrong with drinking, but you can't get drunk! If you are truly of him, God would have warned you about this chick. She is undeserving of you, and you need to just give it to God and walk away by moving on from her. Don't let the devil steal from you by using other people again. You can develop a relationship with Christ TOGETHER if God was in approval of this union, which obviously he wasn't.
Word of advice as another believer to another: Always include God to be the center and the final authority in your relationships. Even in marriage. If God warns you no with a certain person, the answer and final say is no. If she wanted to get closer to Christ, she didn't need to break up with you. All she had to do was get on a fast, and you could have done the same. No excuse. That is a bogus reason I have ever heard. Be glad she's gone so that you can focus on God, rely on him to shape you and mold you into a man of him and you will come across another woman who is worthy of your time. God bless.1

It's very painful to be left but there is a solution:
Stop trying to figure out her motives. She did what she did and she is completely entitled to do it. You can't really explain most of your own feelings anyway so it's well beyond your powers to try and understand hers.
You had a great time together, you must find a way to think about this in a positive light and not judge her. If you judge her, you're judging yourself too and that's not good,
So relax, find other things to think about, and let her go. She will be just fine. I know it's not easy to hear but she will.
But you will too. Just give yourself time and you will be much better. You will, as a result of this, meet someone even better than her.
I hope this helps a little bit.
