Hi Allison,
There is nothing wrong in feeling disappointed that your match wasn’t as attractive as his dating profile showed upon meeting him in real life. We are all human beings and most of us expect to be attracted to who we choose to date.
You aren’t a bad person for being disappointed nor should you try to come up with some way to get past physical appearance.
You like what you like and the last thing you want is to start dating someone you aren’t physically attracted to because you are trying to ignore the fact that you aren’t physically attracted to them. This never ends well. You just end up leading the person on and wasting time.
Think about doing a video chat before meeting future matches on dates. This really helps in allowing you to get a better sense of what your matches look like in real life without the aid of well-taken photos.
