I've posted this question here because as far as I can tell this forum seemed to be the best fit.

About 3 years ago, I developed a close friendship with a woman in her late 30s. We were acquaintances as she was a neighbor at the time but once we spent time talking, we developed a friendship. She was coming off a long-term relationship at the time and was kind of drifting. She had a job that she ended up quitting and was living on her savings. Having her come into my life was providence. I live in a transient area where it is tough to make and keep friendships. Shortly after we became friends, my husband and I went through a very bad time with our daughter and my friend was there for me. I, too, was there for her as she was working through her problems. We gave her items for her apartment and she was a frequent dinner guest. Truly, I enjoyed being able to help her out because in my younger days when I didn't have money, there were those who were kind to me and helped me out. So I was pleased to pay it forward.

Well...fast forward to 3 months ago. She got into a relationship with a man who is in the process of divorcing--no kids. They knew each other through a work situation for quite a while but then things blossomed and began moving very quickly. Within 2 weeks of starting the relationship, they decided to get married and she agreed to move to the other end of the country where his family is. After they move, he has to work overseas for a few months--leaving her behind.

I know when someone starts a relationship, their main focus is on cultivating the relationship and for a while, friendships take a backseat. I told her that I knew the he would be her first priority. A few weeks ago, she moved from her apartment and into a friend's house. I last saw her over 3 weeks ago when she came for a visit. We talked and she said she would call in a week. 2 weeks went by and no word. I called and got her voice mail and ask her to call back. Nothing. So I called again a few days ago and left a message asking if everything's alright--was she sick? Did something bad happen? Did she move already? But she said she would definitely call before she moved. Still no return call.

Now my question--where do I take it from here? I've never met the friend she is (was?) living with but know her name and phone number (my friend had given it to me when she was housesitting there once). Do I call this person and ask what's going on? Or do I leave things alone and hope my friend will call? I don't want to be needy or appear to be controlling but during our friendship, we kept in touch far more often--even when she first started dating this guy. We even got to meet him and both thought he seemed nice and let her know this.

For the record, I feel she's rushing things with this guy but have said nothing to her. (Some of her other friends told her she was rushing and that only made her angry.) I'm happy that she has found someone and do wish her all the best--and have told her this. I've learned not to ask too many questions as she becomes defensive no matter how inocuous the question. Such as--when's the wedding? When are you going to move?

Any advice? Thank you!
