I was in that trial separation situation back in the early 90s, and it broke my heart as I found myself suddenly apart from the girl I'd known and loved since my schooldays, and my two young kids, she didn't even give me any reason for the separation happening, i felt devastated ..... i was in my mid thirties, and it took me a few years to get comfortable with life again, but time is a healer, and 33 years later though i still occasionally look back on the parting with deep regret, i don't dwell on it, i just get on with my life.
At the end of the day you can't force someone to love you, or want to be with you ... they have to WANT it as much as you do.
