The biggest piece of advice I can give you is to use a timeline I recommend for dating: The first three months of dating anyone should be with the goal of simply finding out if you want to continue dating each other. And, you should assume he’s playing the field, as you should be as well. What this does is put your focus on learning about each other and really getting to know each other and yourselves. If, at the end of three months, you want to continue dating, you should use the next three months to decide if you want to be monogamous. Again, this takes the pressure off the relationship and lets you focus on getting to know each other. What you’ve learned in the three months you did date him is that he either wasn’t honest with you about playing the field, which he was doing, or that he realized he just wasn’t into you — and he jumped the gun on committing to you which may have seemed romantic in the moment, but wasn’t a good move for the long run. Dating smart means slowing things down and really getting to know each other.
The reason he’s contacting you now is because he may want more of the same, and because you didn’t blow up his phone he thinks you’re okay with his behavior. If you do decide to date him again, make it clear that you’re not interested in a commitment to him until you get to know him a lot better, and do keep your other options open since he probably is, as well.
I hope that helps! 🙂
