I had a conversation with a 52 year old man just a couple of days ago that went south very quickly. some guys are jerks no matter how old they are, they don't get better with age apparently. seems they just get better at reeling you in with the nice words and get you talking before they show their real colors.

I think you are a nice looking woman, I agree the first few pictures you used were not flattering, I personally HATE to take selfies, I look horrible in them most of the time...angles, phone too close to my face, lighting is bad...if I take them outside my eyes are nearly shut because of the sun, inside at night too many shadows from the indoor lights. It's tough!

Perhaps get a buddy to help take some informal shots similar to your last one?
Much easier to get a nice smile with someone else interacting with you too.

Don't let the jerks wear you down, there are SO many of them on these sites...why do you suppose some of them are single or divorced? I wouldn't have wanted my EX on a bet and I feel for the woman who gets involved with him.

It seems a lot of folks have met good guys online, hopefully you and I will also. I wish you the best!
