feeling appreciated

you know ever since I first had sex with my boyfriend (which was months ago) I've been a little clingy, and it's not necessarily anything he does but I get insecure sometimes that he's going to suddenly fall out of love with me one day (it's more the fact that I live on campus and only see him a for a day or two a week now to almost everyday, it makes me feel sorta distant) and you know when you just first start dating you're up each other's butt and you're super affectionate and it can sort of dial back once you get comfy, just when I was starting to feel unappreciated and mention that he's not as affectionate as he was before he gives me a smile and says "I love you, when i think about how you're there for me, it means a lot and I know why I love you so much. I just might have to marry you someday" and I felt warm and fuzzy and in love but also like a bitch for internally wanting to strangle him until he told me how important I was, and he did it on his own.
