I met a guy at work we were the best of friends at work, we chatted about everything from family to sex lives we started dating after a year and a half but 6 months since I left work i feel we no longer click romantically.

What's meant to be is meant to be, if you want that romatic feeling back, you need to find time and hang out with him more, because if you spend enough time apart those feelings will fade eventually that's just how humans work, plane and simple.

Often times sexual attraction can fade after around a year of being together, if your head isn't saying you want to be in it, don't force it accept the truth.

Relationships take work... romance has to be created. If this is your ONLY problem in this relationship and you feel you need to end it, then so bet it.

When problems arise, those who communicate and work through things together come out on top. Have you talked to him about your issues? You have given limited details.. no one on this website can tell you that this should end by only reading ONE sentence about a friendship/relationship that appears to have gone on for at least 2 years now.
