So I dated this guy who I met on match on & off last year.
Hi Vexer and Age of Acquarius.
Something similar happened to me. I went out with a guy a few times but we weren't really a good fit. We did get along great, however, and decided to stay friends. I offered to take new pictures for his profile because the ones he had up were awful. I brought my camera and lighting equipment over and we got some really great shots.
Then when I started dating other people he sort of faded out. When I asked him what was going on he got kind of nasty and told me he really just didn't care about me at all. That hurt. A month later I was on Plenty of Fish (a different site than the one we met on) and it shows pictures of people in your area who are online and I saw a picture I had taken of him. I was pretty annoyed.
But really they are his pictures, and he can do what he wants with them. It doesn't make difference to me either way.
Let it go.
