I would not date JUST because your ex is and you want to keep up.

I would NOT date just yet if your child is being exposed to a boyfriend so early. I would be a consistent and stable presence in your child's life. Don't date. Figure out who you are as a divorced man and dad. Put your time into having everything when your kid is with you safe, stable, routine. I would give it at least a year and depending on how he is adjusting then i would consider. I would graduate and instead of dating focus on career networking groups.

I would NOT try to meet women at the bar. If you do want to try to meet someone, I would go another route. you don't want a barfly. You will also attract a different caliber of women as a professional vs a student.
