I think I love him

I’ve known my boyfriend for like 2 years and I’ve fancied him like crazy the WHOLE time, and even tho he went out with one of my mates I know that they never did nythin and they broke up after like a week. we have only been going out for bout 2/3 monthsbut its quite… intense? we were like best friends before we started going out so we know everythin bout each other and we are a perfect match

I have only kinda realised in the last few weeks that I think I love him, and the more I think about it the more certain I am, I would do anything to make him happy and he means everything to me. but how do I tell him?? I know he really likes me, but I dont know if that extends as far as love

im terrified of telling him and bein rejected (or even worse him sayin he loved me too just because he thinks he should)

and I dont even know if I should say at all, im quite traditional, and I think that its kinda up to the guy to say it first (just like its right for the guy to ask out the girl etc)

helppp!!! ny advice welcome xx
