I (28F) think my husband (29M) is stuck in the past. How to address?

My husband (29M) and I (28F) have been together for 8 years. 4 months into our relationship, we moved in together. 2 years later, we had a kid. The whole time we have been together, we’ve been as socially active as we can be with the schedules we have (I work 40 hours a week at a hospital, he works 40 at a school).<br><br>I’m worried that all the milestones we’ve hit as a couple have caused him to think that our lives are already over. Ever since we started living together, he almost completely stopped doing anything socially with his friends. Over the past few years, I’ve gotten very close with his mom, and she’s also expressed that she’s concerned he’s not making an effort socially as he used to.<br><br>I work very hard to provide for our family, and I believe that since we both work hard and provide, we each deserve to go out and do things we want to do. It’s not uncommon for me to go to the gym, or meet coworkers for drinks/happy hour, see a show, etc. It seems like my husband gets home from work each day and is content to just sit on the couch or his computer. He occasionally goes to a sporting event or something with a friend, but only if he’s asked, never if he puts in the effort.<br><br>I want to live a fun and full life. I’m not sure how to express that to my husband without him becoming defensive about being called lazy. <br><br>TLDR: Husband and I have hit several milestones together (moved in, had a kid, etc) and it seems like he thinks that he can just stop doing anything enjoyable since he has pretty much all he’s ever wanted. I don’t feel like I’m where I want to be in life, and I want to enjoy myself with/without him.
