A man who reallllllllllly liked a woman wouldn't give her 2 months off while he finished his house. He'd be too scared she'd be snapped up by someone better.
If you do want him to come back in the future, silence is the best way to make that happen. The silence will really really GET to him and make him constantly wonder/panic/worry what you're up to.
I read a dating book years ago that mentioned something called an 8-Week Wait. The author (a psychologist) said it takes men (sorry to be sexist and lump all men in together) eight weeks to process the loss of a relationship.
So when a man dumps you, you vanish silently and just mark a spot on your calendar exactly eight weeks from the break-up. For the next eight weeks, you do NOTHING. No contact, no re-reading his emails, no listening to his old voicemails, no talking to his friends, nothing. You simply hurl yourself into YOUR LOVELY LIFE and make no contact with him whatsoever. (If you do make contact, you have to then re-set the eight weeks and start again, from the date of that contact.)
After eight weeks of not hearing from you, a man will FINALLY realise how he really feels. And then (usually) pop back up trying to re-establish contact. She said it was often 8 weeks to the day.
Try that? Eight weeks from yesterday takes you to Wednesday, 3rd September. Don't contact him at all in that time. (If the urge to contact him gets almost irresistible, tell yourself you CAN contact him after Sept 3rd, and that if you do it before, you have to re-start the 8 weeks from the very beginning.)
In the meantime, spend your time thinking about friends, work, family, exercise, beauty, doing fun new hobbies, meeting new men on Match, reading really great books, working through a list of the 100 Best Films Ever Made, writing a screenplay, learning to waterski or fire-eat or rock-climb... Anything Except Him.
Then see! The author made it found INFALLIBLE. And if he DOES come back by. Sept, you'll know a) that he came back of his own accord, b) that you handled yourself with elegance and grace and steely dignity, and c) how you really feel about him after 2 months focusing on you.
