When is the right time to tell a guy you love him?

Well I'm not expert but I'd say when ever you feel ready and when ever you feel the time is right. i know that probably sounds like a cop -out though so here are some tips for you:

-though it sounds dumb, make yourself a good old fashioned pros and cons list! lol it will really help you sort out your thoughts.

-only say it if you feel sure he's going to say it back cuz otherwise... awkward! lol

-look into his eyes every chance you get and see if he does the same. observe his body language and make sure he doesn't seem uncomfortable. and know your guy too cuz different guys have different ways of showing affection and some are just awkward by nature and some things may be misconstrued if your not careful

i hope this helps and good luck, and if all else fails, wait for him to say it first! lol
