There needs to be balance in life. So, yes, I think you are saving too much if it is impacting your ability to find balance and have a spouse and family if you want one.
I married a man who was always concerned about saving and making more money. He was so concerned about it that it effectively destroyed our marriage because he wouldn't compromise or seek to work together to achieve financial goals. We are now divorced and our children have no respect for him. He spends most of his free time looking through ads and trying to figure out the best way to save that extra penny, but didn't want to spend any of that effort on his relations with the other humans in his life. We could have never worked another day in our life, but it was still not enough for him and still isn't. I used to tell him that all he would end up with was his money, and that is pretty much what he has.
Please make sure that if you find someone you want to share your life with, that the two of you talk about money and that you are on the same page. Also make sure that you are willing to compromise in a relationship.
Edit to provide examples of what I mean:
1. I do craft shows for a side gig, not his thing, I get it. However, at the end of one of them, I was running a fever and asked if he would spend an hour helping me tear down and pack up. He refused because he had to go get a $10 water bottle that was on sale at REI. He also took our teenage son with him and wouldn't let our son help me.
2. I had surgery. He left me alone on the day he brought me home because he had to go shopping for the tax free weekend. It was more important to save those tax dollars (probably less than $100 savings) than to be there to take care of his wife.
(obviously, this is all from my perspective of a 21 year marriage)
