There's always options and sometimes those also bring tough and challenging decisions.
So I'd suggest it would start like this:
- Absolutely no physical contact and that includes cuddles, massages etc
- You want friendship and conversation only
- Make sure you let him know you're going to start dating again
- Start to date. Don't let this falter or you'll likely just want to be with him and fall back into old habits
Some of these things might then crystallise the situation in his mind and allow him to reach a proper conclusion on whether he wants to be just friends with you or something more.
Are you committed enough to do this with a clear head?
