Hi guys 
Normally, I would just talk to my close friends about this, but when I try... well... I think they just love me too much to tell me the harsh truth because some of them do think of me as fragile, which I suppose in a way I am. I'm hoping I can get some advice from some of you guys because I really value a lot of opinions on this forum.
A really strange pattern has developed in my life over the past six or seven years: I start dating someone and the interest level on their part is extremely high. We have a great time together for a while (the longest time was a year and the shortest about two weeks), until all of a sudden, communication halts. I just get completely cut off. In most of my six or seven experiences with this, the other person has thrown around the "L" word; the most recent occurrence being "do you love me yet?" said after sex a few times. It's to the point where I'm terrified about the next time I do love someone, I won't be able to tell them because it's hard to trust anyone not established in my life.
Some examples:
A couple of years ago, my boyfriend of a year dumped me completely out of the blue and without any kind of clear explanation; the day before that he had left a note for me saying "I love you" in the coffee maker. We had taken our time falling for each other (we were friends for a couple of years before becoming a couple), but he told me he loved me for the first time less than two weeks after we became a couple, and we were gung-ho. We took several vacations together, we knew each others' families, etc. And man? I was SO in love with him. I literally almost died as a result of that dumping, and I'm definitely no angsty teenager.
A few months ago I was dating someone I really liked. I was having a blast, and he was stuck to me like a bikini. A day after almost having sex, he cut off communication.
I've been dating a guy now for three months. He's been all about me; going full-force. In this one, because I don't want to be insanity defined, I've held back a bit, but I've been warming slowly, and now I really like him. He came over Monday night after work to hang out with some of my friends, and then we were supposed to have dinner Tuesday night before I left for Vegas. He got stuck in some meetings and dinner didn't happen, so I told him "no problem- I'll see you when I get back," and he said he was sad about missing dinner. Since that text from him on Tuesday, he's pretty much frozen me out. He's not responding to texts... like, at all, and I swear I've been very sweet in all five of the texts I've sent that have gone un-acknowledged.
These are just a few examples! I don't get this, you guys! I'm sweet, fairly attractive, and definitely fun. What is it that makes these people do this? Am I doing something to cause it? I mean, this most recent one has had several long-term relationships where he hasn't done this, so why with me?
A few things that might be pertinent:
-I'm not clingy or needy; If I really love someone though, I like being around them as much as possible. That doesn't mean no boys nights or whatever, though. I think balance is important.
-I'm 37, and I definitely do not want kids. Marriage is something I would consider, but it's no priority, and I'm not willing to get married until equal rights are attained in the state of California.
-I'm financially independent.
-I require lots of time with my friends, and make sure I express my ideal that my partner would be marginally close with them too. I rarely say that in words, but make sure I invite whomever I'm seeing to hang out at my Friday night get-togethers, and to invite their friends. I have had the one complaint from one guy I dated that my friends are TOO ingratiated, but I didn't like that guy (two dates), so I blew it off.
-I don't work and therefore I have lots of free time and I tend to spontaneously take a trip to New York or Mexico or anywhere outside or in between. I think that garners resentment from people sometimes (my mom resents me for it, for example), but I don't know that for sure.
-I suffer from pretty severe depression, and I'm unmedicated. It occurs to me that I may appear fake to people who don't know me very well because I'm extremely cheerful most of the time. When I'm not, I go off by myself so as not to burden anyone else with it, which I realize is a wall and maybe not so good for relationships.
Thanks in advance for any help, especially from people who have frozen or have been frozen out. It's truly an awful feelings; no closure, no answers, just a hole where plans and promises used to sit. It's so strange, but I'm the common denominator, so...
TL;DR: I'm unlucky in love and there are patterns, though I can't figure out how they fit and what I can do about them.
