I had nearly forgotten but I used to have a really hard time telling my family I loved them too. For me I was overwhelmed with anxiety for fear that I would tell someone I loved them and not mean it. It's kind of silly because I love my mum very much (incidentally I am now at the opposite extreme and tell her regularly and get offended if she doesn't say it back!). I feel uptight about telling SO's that I love them but I do it anyway because I want them to know that I care. It just stressing me out rather a lot! Oh yeah, and you aren't being annoying: it's always nice to find NT's who want to better understand Aspies!
