@LuckySantangelo35 oh of course, I totally agree that you shouldn't lose yourself in motherhood.
But ultimately the things that make me who I am are all things that I do on my own. I am an accomplished musician and a very amateur but enthusiastic visual artist. I love cooking, reading, going to the opera and art galleries. I try and do these things as much as I can now I have a baby, but the reality is that as well as all these other things I am now a mother. I love being a mother much more than I love playing the piano or going to art galleries! So if two priorities are conflicting, being a mother always takes priority for me. It's not because I feel like I have to, it's because I just love it!
As for my friends, some of them share my interests so sometimes we engage in them together. Usually we don't, though. My closest circle catch up over FaceTime at least once a month. Some of those friends still go out clubbing together, but I don't join these days. I am still just as close to them all as I ever was.
I make time to meet non-mum friends usually once twice a month at weekends. This isn't because I feel like I can't do any more, it's because it's as much as I want to! I have a lot of friends, so yes it means that individual friends get seen infrequently, but we text often. We don't do much exciting. I could sit in a room and talk to my friends for hours and hours, I don't need to find some activity to make it interesting! And yes, my baby often is around too because they usually want to meet up with us all as a family.
My friends seem very interested in my baby, which makes me so happy. I never bring baby stuff up unless they ask, which is because I'm anxious that people think mum-related stuff is boring. But they're my friends, so they care about what's important to me, whether it's boring or not. One of my friends has an intensely dull corporate job that she talks about often - but because it's her job I am genuinely interested because I love her and I am invested in her life!
If this makes me a mummy martyr then so be it, I'm not sure I really care. I am happy, content, and I have a lot of friends who love me for me and not because I happen to be interested in accompanying them to whatever event or activity they want to do.
