A bit of background first!
We had been friends for about 5 years and spoke and spent time together regularly. Loved spending time with each other (didn't do so with partners as they have totally different personalities) and we regarded each other as best mates. We didn't have a 'break-up' but she just seemed to not bother as much. I didn't chase her for her friendship - a true friend shouldn't have to do that but pretty quickly the relationship between us broke down.
I think the final nail in the coffin was me becoming pregant with dd1. DH and I were sucessful in conceiving after a course of fertility drugs and after 8 years had our long awaited baby. She and her dh tried for a baby unfortunately due to her dh health problems was unable to concieve. Getting pregnant almost turned into an obsession for her and it must have been upsetting for her to hear about my pregnancy. She sent me a card after dd1's birth and nothing when dd2 arrived 2 years later.
Now, I hear that she has recently adopted a little girl. I feel like I want to congratulate her, send a card and a present which will show her how happy I am for her and her dh but the other part of me wants to not bother as she couldn't be happy for me.
What would you do?
