I was thinking about this yesterday because my FMIL texted me a very sweet text about hoping my day goes well and that she loves me. J's family is very touchy-feely and always end phone calls with an "I love you", and hug each other goodbye when leaving a family gathering. I think it is nice and they are very inviting people, but I always feel really awkward saying "I love you too" back. My family is perfectly loving and close but we have never been an "I love you" saying family all the time. Does that make sense?
I guess I just never say "I love you" out loud except to J, and sometimes my parents if the situation seems to come up. For some reason it makes me uncomfortable to say out loud to other people. Is that weird? Haha am I heartless?

Honestly I do feel love for my ILs, but saying it just feels strange to me. Am I alone in this? Are your ILs more affectionate (or less) than you?
