Nicole - I don't think that there's anything wrong in not wanting to do online dating and going to bars etc to meet up people and find dates that way. However, there's tons of other ways to meet people and socialize. Meet up groups, parent groups, hobby groups etc. But, I would definitely talk to a therapist about everything because I feel that your reticence to do this is probably based on fear of the unknown and getting rejected. I maybe off-base here, but I was told by 2 people when I said I wasn't interested in dating right now and they both came back to me about the issue of fear. I hadn't considered it and they were right. That was definitely a major reason aside from others that is holding me back from dating.
If you don't want to do casual dating until you're D, that's totally understandable. That's my position right now because I don't think it's fair for the other person when I am not 100% committed to being open and exploring casual dating or a relationship. But figure out what is going on emotionally for you and then see where it leads you.
I would say at a minimum try and expanding your social circle and focus on socializing and meeting people without any agenda. That's my goal this year to just be more social and explore friendships. Take it a bit at a time.
