Me and my love are in a distant relationship, and now we are not communicating for several months? Does he still love me or there is anyone else in his life? Should I stay or move on?
I can't answer all the ancillary questions you have.
He may still love you, since he as Jupiter receives you/Merc well in Pisces, Pisces being the sign that Jupiter traditionally rules. And we see you are very interested in him, since you/Merc are in his/7th house.
But despite this, I don't see the relationship working out between you, since Merc and Jup separate from a trine. It is like the opportunity for you to come together has passed. Restating that theme of separation is Moon and Sun, which also separate from a trine.
I think it is time to move on; I would not be misled by whatever feelings may still be there.
