Rethinking Rejection

OK, so this is my 3rd try at Match in 4 yrs. And my big question is- what is with all the flakiness and insincerity? I've had a few experiences that have left me so frustrated that I've resorted to venting online. My 2nd try was last yr- a 3 month trial. I'm 50, attractive, and very young looking. I have tried online dating because I'm in CA only a few years and don't have any female friends my age to hang with. I work with mostly young professionals who like to hang out at the bars with others their age. The guys at work who are interested in me are way too young. I've been told by a few female friends that many of the young men I work with have crushes on me. So, I can't be that bad, huh? Well, last year I went on one lunch date with a guy from Match. He seemed very nice and told me he had an awesome time and that he wished he was getting ready for our lunch date again (meaning that he wanted to do it all over again). We agreed to meet after work the following Friday and he gave me directions to a place by his home in Little Italy Downtown. I called when I left work to let him know I was on my way and he texted me, "I'm too tired." That's it. No apology. Nothing. Never heard from him again. Date #2: Another seemingly nice guy emailed me & we chatted online for a bit. He was a school teacher in my town and seemed nice. He gave me his number and asked that I call him. I did and left a voicemail with my tel no. I never heard from him. I didn't renew my subscription until last month when my 16 yr old daughter created another account for me because she feels that I need to be proactive and try again. Besides, it seems that everyone is dating online nowadays. So, I tried again and I received many emails & winks but I saw a few guys that caught my eye-nice smile & profile. So, I emailed one guy regarding a funny picture he had posted. I got a response asking to meet this weekend. I texted him back and he called me immediately. I said this weekend would be fine but that I would call him right back because I was getting ready for work. He said, sure, and that he, too, was busy running errands. I called him back and left a VM. I texted him today to ask if we were still on. I haven't heard from him at all since his call. And he seemed quite happy when we talked about my being available this weekend. I don't get it. There have been a few other times when I made a connection either by email or phone and never heard from the guy. Those things didn't happen in NY when I first went on Match 4 yrs ago. Is it a California thing? Avoidance? I would really like to know because I keep going over it- is it my voice? (I don't think so, I have a pretty sexy voice). I'm well-spoken, intelligent, independent, and have a great career. I know that some of you may be thinking "there's prbly something wrong with her", but, I can honestly say that I am above-average in looks and people are usually floored when I tell them my age (they usually think I'm in my 30s). I have a good sense of humor and I'm pretty easy going. I usually let the guy do the pursuing (that's the best way to see if they're really interested). I won't ever chase after a guy. If you're going to judge and tell me that there's something wrong with me, please don't. I've been beaten up pretty badly today. I just don't understand why men just don't say, "hey, thanks but I'm not interested" or "I've met someone" or make something up. Just leaving a person hanging after engaging with her and giving the impression that you're interested is cruel. Maybe I haven't been in the dating field long enough. Thanks for reading -- Lovinglife
