Brian's older boyfriend (Evan?)

[erdmut1]

Hello, I'm looking for a series (believe there was also a follow-up series) where Justin learns about Brian's boyfriend from the time he was in college. Justin is convinced Brian was in love with this guy (I think his name was Evan) and become very jealous - meanwhile, the ex-boyfriend wants Justin back. Of course it turns out the guy never loved Brian. In the sequel, the guy works a free-lance gig with Brian, and Justin gets jealous again.
thanks!

FOUND (and even better than remembered)! It's "Love Remains" by blissink
The sequel is "Saving a life"
