I hate to be blunt but I think you hit it right on the head, it's jealousy. My sister actually went thru this a few years ago.

My sister was near 40 at the time (38) and finally met a great guy after going out with guys that would emotionally hurt her or just use her. My sisters group of freinds were just like her, most of them mid to late 30s, nearing 40s, single career minded women, with either no time to date or just bad luck meeting men who were jerks.

So finally she let the cat out of the bag and told her friends she met a great guy and it was serious and she couldn't believe this was happening to her (my sis is pretty attractive physically and all her life guys just wanted one thing from her so she was really excited the guy she met wasn't like that). That's when as she described it, most of her so called friends turned on her.

Some like your experience just wouldn't talk to her anymore and tell other women to shut her off. Some in her work place would use past personal conversations and try to pit her off against someone else in the workplace or an old ex. From what she described to me, it got really weird.

So she asked me for some advice, and from analyzing the situation, and I think it's the same w/ yours, I told her that her so called friends gave her an ultimatum, us or your new boyfriend!

So sometimes we have to learn our lessons the hard way, and she decided to move on with the next stage of her life and ditch most of those old friends. Now some of the old friends were happy for her, and she's been in touch with them, but the poisonous ones she hardly interacts with, maybe if she has to like at work.

My sis just married that guy this past summer and has plans to have children. She is happy, and I hope some of her old friends are happy for her too. So If the guy is right for you, makes you Happy, and you think you have a future with him, it's your choice who to pick - or better yet, your friend will come around and be happy for you.
