I dont do well in large groups, ever since i was a baby. Ive never been able to break that habit. And my mom had a huge family, my dad had a few people and we went and did family stuff regularly every month so it wasnt cause i was sheltered and never saw anyone... But i get uncomfortable with my fiances side all the time. They have a saying "family isnt always blood." And for me thats hard cause my family is very huge and forgiving but we have had alot happen to where in cases i dont always believe it. I have true friends that have been with me for decades.. But i just feel we are really close and i would do anything for them, but thats it. Me i get so annoyed when i just want intermediate blood family only for certain things. And my in-laws invite their overwhelming amount of friends. Now in no way am I saying what my fiancé's family believes is wrong by any means necessary! I know a lot of people that believe in that saying is well. I'm just a little more forward about my feelings, and I usually tend to be more protective. But with having a baby on the way and moving out into weeks, budget is kind of tight. And I find it extremely annoying when I get lectured from my in-laws about why I don't want to spend the extra money to send baby announcements, or pictures to their friends. I know the intermediate blood family and I automatically send anything that I take to them. I was always raised with making sure your family is always updated on happy news. But I do not feel like shelling out another $50-$100 just for my in-laws friends... I've tried suggesting maybe they can try paying for their own? Or at least help me out with stamps or packaging.. Maybe I'm a little overwhelmed, and I know it might sound cold to some. But I am just trying to do the best I can for the intermediate family only, on such a tight budget. And I alone in this? Or do I just need to relax and breathe and just shell out more money..?
