Hi Kristen,
I hope you feel better soon. It is evident that this is not about a new girl he met, it is about he has a deep problem. Unfortunately, as we have low self esteem (me too) we always think we are the reason for rejection. But, I am sure you are not the cause. Of course this event is not a good thing for you, either. This is not helping to boost your esteem. I am very sorry you have to go through this. It is good, though, that you are looking for help. I have lots of hope for you and think you will overcome this. Keep posting, please.
