soooo sorry.. I had a man for 20 yrs. Ended badly so kinda know your loss... May I suggest:
1) be with CARiNG friends regardless of their orientation. 2) Review Your GOOD values/interests and remember/focus on them!...
3) when you're over your initial deep pain... slowly start associating with pple/women who have some common interests... and.
4) BE your Authentic true self!... I know a few gay couples, 2nd relationships for each, who know that being AUTHENTIC can make a difference; tho many (gay-men) haven't quit learned it IS OK to be HONEST,, AND,, KNOW that each person needs to compromise some. As Dan Savage said, each person hopes to start @ 65% likes of the other, and visa versa... then over time people may come together... OR... "what's the Price of Admission to the relationship?.. There ARE certain things each do to the other.... yet if the other's (mine) deficients are X%, does that person offer enough goodness to overcompensate for the negatives?... kinda like: if the other LUVS rollerCoaster: The other may LOVE them. I/you may hate it,,, but does this cuz I know the Other provides enough GOODness that is better than the rollercoaster, negatives? It's about Balance AND Honest caring communications !.. persevere!!.
