She asked for a divorce in December and I lagged on my acceptance since the physical separation didn’t really materialize. She just moved into a trailer on the property a couple weeks ago but was still hanging out with me at night. Nothing romantic but friendly(i stupidly fell back in love with her). But she just started seeing someone last week and suddenly no longer around. I know I didn’t take it serious until now but damn hearing her come and go just breaks me. Not sure how to cope. She’s been my best friend for decades and I’ve lost her. I’m not begging for a change of mind though I do love her more than anything. She’s not wrong for her reasons. No fault in either party. We were young when we started and never developed our own identities.

How do I keep my feelings in check and be mature?

I hope I’ll gain clarity over time but right now I feel empty with no identity.
