Am I being overbearing? Will this push our friends away?

I have Asperger Syndrome (an autism spectrum disorder) and often have trouble with social protocols. I have never really had any friends who I could just call up and ask if they want to go to dinner or a movie or just hang out. I have been married for almost 4 years to an older man and I usually look to him for social cues. We have recently (5-6 weeks) made friends with another couple (also a younger girl/ older guy pair). We both really enjoy their company, whether out to eat, at a movie, or just hanging out at home. They seem to really enjoy being with us as well. The problem is that I am always the one who communicates with them and suggests getting together, never my husband or the other couple. They have always accepted my invitations except one time when their child was ill, and we always have a great time. My husband told me I might need to back off a little and let them extend the next invitation, because they might think I am being overbearing and too involved with them and that could push them away. I don't want to lose these friends, but I thought we were all having a good time here. I don't want them to think I am not interested in getting together just because I am not making an invitation. Should I just continue what I'm doing and see what happens, or should I listen to my husband on this one?
