Need some Friendship advice...

My husband and I were friends with this other couple for a little over a year. We used to live in the same apt complex and about a year after we had been friends, they started buying the same things as us and we were a little creeped out. (it was almost “stalker-ish” ) I always felt like they were judging everything we did… anyways, long story short - we ended up actually getting pregnant and buying a house and moved just ten minutes away from them, but then everything changed once we moved. She sent me this huge email about how I put all of my time into the house and my pregnancy and how we sort of stopped getting together as much. She wanted to get together every week! Where I come from - getting together with your friends once a month is a blessing! Anyway, that email really hurt me because my new house and getting everything for the baby was my priority and I dont see anything wrong with that.

So… I told her how I felt and we sort of made up but it was never the same. she wanted to throw me a baby shower a few months later… however, she stopped emailing me once I told her that I didn’t need her to throw me a baby shower because my friends at work were already throwing me one (but I was really nice and thanked her for offering) and she was totally fine with that and said “we’ll have to do lunch sometime then”… but then that was the last I have heard from her. it has been 8 months since I have talked to her. They didnt even send us a congrats card or gift for our new baby. you would think if they wanted to be friends they would show us they cared…? I don’t really know what happened or how we got to where we are now and I don’t know if I should try contacting her again or just get over it…? (I really want to be friends with her but its been so long, im not even sure she would consider replying to my email… I need some advice please… what should I do?
