I was "single" for 2 weeks or so before I met her. Finding dates on Match or OKC or POF has never been an issue. Finding someone I really feel connected to is. The amount of other options literally a mouse click away may be to blame. I honestly haven't figured that out.
I had a really bad break up in March of 2012. I took a few months to try to collect myself and started dating again in July. In that time I've used all 3 of those sites on and off. I've been on what I would estimate as ~40 first dates. Of those I felt compelled to ask about 25 or so on second dates. Of those 25 only one of them didn't want to see me again, but none of those ever lasted more than 2 months and only 2 of them made it that far. I'm starting to get frustrated, exhausted, disenchanted and apathetic towards dating. The amount of women close to my age (30) that still have no direction and haven't established themselves is laughable.
When I was younger I was very noble and idealistic about dating. When I was 23 I met two girls over the course of a weekend. I liked both, both liked me but I refused to date two women at the same time so I chose one. We dated for 3.5 years and it ended amicably. 2 months later I started using Match and had 2 dates lined up for one week. I went out on the first, decided I liked her and canceled the second date. We dated for a year and half and that ended horribly. It was devastating because I thought she was "the one". Up until that point I always thought dating multiple people even for a week was for insecure people who needed some form of egotistical self-validation. After that breakup I thought "fuck, what if one of those other girls really was the one, I'm never letting that happen again". The problem is I really hate being alone and really want kids. The realization over the past year that there really are plenty of fish in the sea is comforting in a way but it's fleeting and ends up just making me feel like a dick. I also know I am not the type of person to ever "settle", so that leads to me dating lots of people rather than just trying to "make it work" with someone I'm not fully invested in.
