Online dating????

So I am 24 and I am separating from my husband of 2 years and we will be getting a divorce. We have known each other for almost 10 years, and dated for like 6 and then were engaged for 3 1/2 years before getting married and now he is completely different and won't help pay the bills but always spend all the money on weed and refuses to do anything else or change his habits.
I want to meet some guys (although I'm pretty sure that I'm not ready for anything serious yet), I was thinking about online dating because I go to school part time and I work like 1 full time job and 3 part-time jobs so I don't go to parties or bars or anything.
Just wondering if anyone has suggestions for some good dating sites.
