Hi Ginger. I haven't posted before but I had to post after reading yours and Jellybs reply
It doesn't matter if your overweight or underweight , tall short , plain , drop dead gorgeous or anything else. You are you. Quite possibly you are chosing the wrong guys or possibly you haven't come across Mr Right yet but there are plenty of Mr Rights out there.
IMHO if your in the mindset that you aren't going to find that special someone , it's a lot less likely to happen and maybe that vibe is attracting the wrong type of guys
