I hear you. Having this same issue, wanting to speak to a man that is only available when it suits him
I’ve been reading a book that’s a little bit on the nose at times but has some interesting ideas. It’s called Exaholic: breaking your addiction to an ex love. It essentially compares romantic love to being as addictive as most other addictions. There’s information on studies that talk about mri scans showing that the same parts of the brain that get addicted to drugs or alcohol are the same parts that respond to seeing images of someone you love. It’s very normal to crave something so intimate that we had for so long.
It’s been helping me a bit understand why i feel the urge to talk to a man still who has been sooooo crap to me for 10 years.
