Hi hive, I need some help and advice on how to proceed with my relationship with my mother.  I will try to keep it short and sweet, I just dont know where else to turn for some advice.  My friends and family dont know what to tell me. 

We have not really spoken since Thanksgiving when she told me her bf of 3 months was living with her and they were probably getting married.  To give you some history, she has been divorced twice and it seems like she rushes into relationships- she knows that I feel this way but I havent brought it up for over a year since her last bf. There was talk over sleeping arrangements for the holiday when she casually mentioned that he lived there.  I told her that I didnt feel comfortable staying there since I didnt know him and that I'd come over in the morning.  She started bawling on the phone saying how I judge her, she justs wants to be happy, she doesnt care what other people think, he's finally the one,  etc.  Mind you, I didnt say anything juding her!  She started attacking my relationship with my longtime BF, my family, and my overall character.  I saw her on Christmas for a few family functions which was kind of awkward, she could not be without her bf for any event and we barely spoke.  She posted hurtful things about me (vagely of course) on her facebook wall then said if I didnt like them then I could defriend her! It is clear that yet again, she is choosing to be wrapped up with a new bf and forget about everyone else but I dont think she knows or cares how this hurts other people in her life.

So here we are in February and she still hasnt reached out to me since she blew up at me during Thanksgiving.  I told her I felt very hurt by her words and actions and I did not get any email back.  She has since completely blocked me from her Facebook! I have no idea about anything going on in her life.  The craziness of this all has worn off but I'm left wondering why doesnt she miss me? And do I want to/should I reach out to someone who would treat me like this?  Basically, I just dont know where to go from here.  We've never been on the outs like this and it's bothering me so much, and even more because it feels like she doesnt care.
