If that's the case then why not do something about it? Doing the same thing over and over again will just end up with the same results.

Why not try and lose some weight? The truth, if you are very overweight ( and I assume you're not exaggerating) then yes that will be a barrier to men wanting to be attracted to you. That doesn't mean there aren't men out there who don't like big girls, but the reality is that you're limiting your chances, and with limited chances, comes the limited amount of decent men.

Looks are important to men, almost certainly at the initial stages of looking for a woman. It may seem shallow, but it is the reality unfortunately. So join a gym, eat healthy, do activities like swimming or running.

If you're clothes are a problem then buy some different clothes. Do you have any girl friends who can help you with this? You claim you don't present yourself in a way that'll draw male attention? Well you need to change it. Maybe get yourself a new haircut, some make up and a nice new dress. You'll be surprised how different and how much better you can look with just a few changes like this.
