Hi, I’ve NC but been around a long time.
A bit of backstory before I launch in to while I feel like this.
My parents divorced when I was 10. I have one DB. My DM remarried a few years after and I have 4 Stepbrothers & sisters. I have 3 DC….DD1 is 10 years older than DD2 and 13 years older than DS1. DD1 has a different dad. I was married to younger DC dad for 10 years but divorced 8 years ago and now live with my DP with my younger DC and 2 of his DC.
We are getting married next year 
The problem is I don’t feel like I belong in any family. I don’t have any contact with my ‘D’F - my choice. He treated my DM horribly and he’s not the kind of person I want in my life, or my DC. That’s not an issue, I’m happy with that.
The issue is all the other family…they all meet up and I never get invited. On the odd occasion that I am I feel like it was because they had to invite me.
Christmas was horrible…obviously due to covid the previous christmas was a bit of a wash out so we were just home with immediate family….but last Christmas my DB, DM, SF and nieces and nephews all had Christmas together (5 miles away) whilst me and DP sat home on our own. When id asked if there were any plans I never got a definite answer, they obviously just didn’t want us there.
Same recently for DB birthday - they all went out for dinner - no invite for us.
Easter is the same, they (including step siblings) are all renting a big house by the coast. No mention or invite for us. I only found out because my Sis in law mentioned it when I saw her in town a few days ago.
My DD1 has a DD. When she was born she was given her other nannas name as a middle name…even though I’m very close to my DD and her DP isn’t at all close to his DM.
There’s been too many times to mention where I’ve been forgotten about or overlooked. My DP parents are great, they include me in things and we get on really well…but his DB doesn’t like me so anything he’s involved in sees me out of the equation.
I don’t know if I’m just wallowing in self pity or if there’s something wrong with me that makes people not want to spend time with me?
I’m close to my DM, we speak every other day and see each other often but never in a group. It’s like my whole family is embarrassed by me.
Anyone else feel like this? Anyone else not included in their family? It really, really hurts.
