When you first spark with someone, get their email or number and send friendly texts or emails back and forth until you get a sense of that person and you would feel comfortable going on a date with them. Once you go on a date with them DO NOT choose your date to be at the bar or some place where drinking is emphasized. Go to a dinner and a movie or a walk in the park thing.
Once the date is over, I think it should be up to the man (chivalry people, let's bring it back!) the next day to do a follow up text at least, I had a great time etc...I think if you do these check in texts or emails they go a long way...If you two are still sparking set up another time to go on a date- dating once a week is more than enough to get to know someone during this getting to know each other phase.
When my clients tell me they started dating someone new, my first thing I say is take it easy go slow. Like seriously, especially if you had a bad track record. Remember that old saying; slow and steady wins the race.
