He broke up with me 2 weeks ago. Breakup was for external circumstances and we still had strong feelings for each other, we were together only 4 months so I still felt like we were in the honeymoon phase.

After 6 days of NC he started reaching out again and I told him it's very hard for me to talk to him at that point. He said he misses me and wants to talk to me and keep in touch for when he is ready to give it another try. We have been exchanging some texts every day but I feel like it's not in our best interest to be in contact at this point. He is still working on the issues that led to the breakup, nothing has changed, and I also have some healing to do.

How can I tell him I think it's best we aren't in contact for a while for both our sake? Should I give him a timeframe of when we should talk again?
