Boy confusion😣

Hey guys, I'm in a state where I have no idea what so ever on what to do.

This guy that I've been sleeping with for 2+ years has told my cousin that he has feelings for me, but doesn't want to act on them yet, as he wants something long term with me, and he feels like rushing in straight away won't make us last. Now thats all fine, he knows my feelings towards him are extremely strong and always have been.

I went away with him last weekend, met some of his family and vice versa and it was all very great, however, he has been extremely, extremely quiet this week, which is never like him, my cousin said maybe he is a bit intimidated by his feelings or something like that, but I don't know.

It constantly makes me feel like I've done something, and I always will 100% understand if he has something on or is doing something, I'm not pushy in any way, because he always gets back to me.... besides this week, where ive heard from him maybe 3 times all week😪

Any thoughts x
