@blnz,
Give him some space. Give yourself (not him) a timetable. Whatever that is - the summer? The end of two months? The end of the calendar year?
Just decide whatever is reasonable (and maybe add 10% to that) and use that as your waiting period. In the meantime, go out and have fun! You are not tied down to this guy
at all. If you want to kiss someone or even have sex with them, go for it with the usual precautions.
You're a free woman.
Once the waiting period is up, assess the situation. Have you met someone you like better? Have you had fun just being single and not dating anyone? Have you missed this guy? Has he made an effort to get back together?
If he has made no efforts, and in particular if you have met someone else or have had fun otherwise, cut your ties completely and consider the waiting period to be over. Do you tell him? Nah; there's nothing to tell.
If he has made efforts, but you're finding you're happier without him, then cut your ties, but this time tell him. Use the old, "It's not you, it's me." Because that will be true – you are causing the breakup because you've moved on (there's no shame in this, BTW, don't feel bad about it and own it).
If he has made efforts, and things are better and he's asked you to be patient, and you like him and want to be with him, then the answer there is pretty obvious, too.
But create a certain date in your head. Be reasonable and be generous and be flexible. But don't make it indefinite.
