It really is. I know a lot of people feel like it's a pain or hassle to get back in the game (especially after a tough breakup), but why not be open to meeting new people? Do you really have anything to lose? You can only really gain a great new relationship.
In the past few weeks I have discovered a great free dating site (changed over since my subscriptions have expired) and have been quite active on it. It's a nice reminder that there are plenty of guys out there that find me attractive. I have found a new confidence in myself, and have a lot clearer picture of the type of person that would be compatible with me in a relationship.
Even when I have gone on some dates where there was no spark, it was no big deal. He didn't call? So what! It hasn't discouraged me at all because I know I have hit it off with others who I'm still in contact with. I have the power to pick and choose who I'd like date. The key is recognizing if they feel the same way or not after meeting them or going on a few dates (guys aren't very direct about that usually) so you don't waste your time with someone that isn't interested... because you deserve someone that IS interested and appreciates you for the amazing human being you are!
I have dates with 2 different guys this weekend, and if I'm lucky one of them will keep sticking around :)
