Most Helpful Guy
An Ex is and Ex. Don't meet him. If you do want to meet him, meet him with your current boyfriend. Let your boyfriend know that your ex wants to meet you. If he is not okay about it - stay away from your ex. If he is okay with it, then ask him to come with you.
You may never want to cheat, but you don't know what his motivation is. Don't let him think that you may be interested because you agreed to meet him.
Stay away would be the best action.
Most Helpful Girl
Do yourself a favour: don't.
He left you walk away and it's unlikely he might have made up his mind over the past 2 months. I don t think he wants to be friends with you.
Moreover, you should avoid out of respect for your current boyfriend.
