What do all these things my man does, really mean?

Few things I’m curious, not upset or worried about:

I thought I’d joke around with my boy while watching him play tennis by not telling him who I was messaging when I was asked. (It was really my mum) He spazzed out (didn’t get abusive at all) but just ran to me, trying to take my phone from me, demanding I tell him who it was, while laughing; does this mean he’s generally insecure, (as he’s been cheated on 4 years ago when he was 17) or just wants to make sure no one’s messing with me?

Last night I decided to confess to him that I’ve been harrassed by prank calls by an unknown male, who makes suggestive remarks. Straight away, he asked me how long this has occurred and why I didn’t tell him as soon as it happened. He also asked me when the last one was; again, is he insecure or just looking out for me?

As I’m temporarily handicapped from walking because of major surgery, he’s been asking me if I’ve had my medicine, how many tablets I’m on a day, if I’ve done everything I’ve had to do to recover, etc. I find it very sweet, but why is he treating me like a small child?

Last but not least, when I asked him what he was thinking when he gazed in my eyes, he said “a lot of things, but one thing I think is ‘thank God I’ve got you’- you’ll find out the rest one day”> what could the rest be?

Thanks heaps to anyone who answers :)
