Dayouth friend

I have a friend whom I'm not really close to, but we've known each other for almost 7-8 years. We never really hang out together, but we've always been in touch. The thing is, he got married recently and now he's posting pictures of him and his wife on every social media platform. My heart tells me to ask him not to do it, but I'm scared he'll respond negatively, asking why I'm interested in his wife or telling me to focus on my own life. So, I muted him on social media. My heart says I'm not doing the right thing, but I won't sacrifice my self-respect. I hate that when this thought cross my mind it unsettles me and have this heavy heart feeling throughout the day.
