H.G.
So many of us are in the same boat, Tina! We moved to New Jersey last year, leaving all our family and friends behind. And even though I talk to everyone daily/weekly, it's not the same. My husband and I both miss having social lives. (He has a long commute, so even with work- it's not easy for him to meet people.) Go to www.meetup.com and/or google "Mothers and More." It really helped me to get into a regularly scheduled playgroup, rather than just classes. Eventually, you'll meet one or two moms that you really click with. I even started my own meetup group, when I felt out of place in the groups around me.
Eventually, I realized I also had to rediscover the pre-mom me, and I am learning not to feel guilty about that! It's so great to take a class (drawing, gardening, etc.) or go to a mom's night out- I'm finally getting to talk like a grown up again. And it's saving my sanity, and my marriage...
Good luck, and be aggressive in the search for your own happiness! As I've gotten less bogged down in guilt, I've become such a better mom. And I think both my son and husband appreciate me more, when I'm smiling and feeling like I have a life (even a small one) outside our home!
