Well my only advice is go for it lol.... Anyway I'm sure u can't stand him going out with anyone else.. and it will be the same situation for him also. And you both are not seeing anyone, so there is no problem. Well fear of everyone coming to know about it.. well try to hid as much possible.. if they come to know then well.. You guys not doing anything wrong. But I warn you having relationship with someone who u spend most of your time... not always good thing... Now if your wondering how i know all this.. Well cause i'm having affair with my colleague . Well it started as harmless thing... now its standing in the door of relationship. Well I made it clear to her that I don't want to have relationship with someone who i can spend time 24X7 and later when situation changes.. it may happends. But fact of the matter is....I can't stand her lossing her... So its very tricky situation and she she next to me remember...Well i feel like its a trap...
