I'm sure that Tiger being FIFO makes the loneliness worse. Solo parenting 24/7 is tough. I do have people that I can go to visit or who will come and visit me, but having Tiger come home every night used to make such a big difference.
After spending so many years working and always having people around, being alone all the time is an adjustment. Sure, I've been a sahm for three years now, but I still miss having company. As strange as it is, I love being alone, however being alone with kids is very different to being all alone.
Whilst I do have people who I can visit, I don't get adult company every day. Ive been very fortunate recently because my BFF hasn't been working full time so we've spent a lot of time together. I have no idea what I'll do when she's back at work full time.
My online friends are the ones who keep me sane and give me adult conversation, without them I think I'd go crazy.
