Don't fit in with friends

I have this feeling like I just don’t have a lot in common and don’t fit in with my friends. We’ve been friends for almost 10 years, through college and now beyond. We’re close to 30 now. I just feel like I don’t have anything in common with them and I feel lonely and out of place sometimes. They all are vegetarians and vegans. I eat dairy and meat. They talk about their food all the time and new vegan items and I cannot contribute to that. They know I don’t agree with it, so I always feel odd one out. I will invite them over, they will bring vegan food to have fun to try it. I don’t want to try it, I eat regular food. I don’t get the lifestyle. I don’t argue with it, I just don’t choose it for myself.

They are all married or engaged, I am single. They are all opposite of me politically. I feel I have to hide part of myself. I have a different view point on relationships and love, I think since I am single, I am more aspirational. I want to meet someone with a good job, stable lifestyle, and with motivation. My friends talk like their guys are this way, but actions and reality proves they are not. One of my friends is engaged to a guy who doesn’t even work a real listed job. He is paid under the table and can’t even buy a house because of it. So my friend is responsible for the benefits, the credit, the house, the cars. It’s a bit crazy. But I try to be supportive. I think they judge me for wanting more in a man. Maybe out our jealousy. I don’t know. I think my friends are all amazing catches to guys. They are awesome ladies and should strive for more.

But even the other night. We went out for a girls night to catch up. They spent an hour just talking about their relationships, marriage plans, boyfriends, travel plans, holidays, but all relationship based. I couldn’t relate, I couldn’t contribute, I just kind of sat there for the first hour as they gushed to one another. I felt like the odd one out. It wasn’t fun for me. I just sat there. Shaking my head with a smile. I’m happy for them. I think again, my girl friends are amazing ladies, but I just feel so disconnected from them lifestyle wise. Its hard to be myself. I feel like they don’t really know me anymore. I feel like they don’t get or care about my struggle to find a man. They aren’t sensitive to inviting me out to all couples events. Nothing. One time they invited me out to a couples dinner. A dinner! I mentioned to my friend that its a bit awkward for me since I am single attending. She just happily said “Well find someone to bring” like its just so easy. Like let me find someone on the street. I wasn’t offended, I just felt more disconnected from their lifestyle compared to my independent one. I do a lot alone and independently. I’m okay with it, but again, I feel like my friends just aren’t on my level anymore, and I’m not on theirs.

How can I fix this?
