i think i'm in love

me and my boyfriend got together in april. we've been together since then, but we didn't officially start dating until recently. i've felt for the past 2 months or so that i'm in love with him. i just don't know how to tell him. i know it sounds stupid, but i'm really worried of rejection or him not saying it back. also, i don't know if it's too early as we just started dating. we say "lots of love" when we're leaving or saying goodnight, but i really want to come out and say "i love you". since that's how i feel. someone help. i really want it to be sweet and cute when i do it. tell me if you think it's too early. give me opinions and advice, help ya girl out

ps i've never told anyone i loved them because i didn't want to until i really meant it so this would be special
