Tips for relationships

I'm in need of some guidance. My boyfriend (23) and I (24) have been together for just 10 months, and I experienced a whirlwind romance that led us to move in together. However, I think I might have rushed that decision. After moving in, I've come to realize that we have significant differences regarding crucial topics like career aspirations, family values, politics, and even our levels of maturity and public behavior. I’m not sure how I missed these red flags earlier—perhaps I was simply blinded by love. Now that I'm aware of these discrepancies, I find myself questioning our relationship more than ever. What once seemed minor now feels frustrating to me, and I’m surprised by how much annoyance I’ve started to feel. Initially, I thought my lack of libido was due to hormonal issues, but I've realized that it's not about a lack of desire for intimacy—it's more about my lack of desire for intimacy with him. When I try to discuss these concerns, he tends to downplay them. For instance, when he made a borderline racist joke in a store, I felt uncomfortable and embarrassed, telling him it wasn't appropriate. His response was that it wasn't a big deal since the person he was joking about didn’t hear. That’s really not the point for me. Here's the thing: he treats me incredibly well and makes me feel special in ways I can’t complain about. Despite his immature humor and sometimes questionable behavior, he is fundamentally a kind person. The idea of hurting him makes me truly sad. What should I do? Since we just moved in together, I know we could break the lease if necessary. Is it too soon to consider couples counseling? How do I express that I feel a lack of attraction to him and that he has room to grow, without coming across as trying to change him? I really don’t want to be the “bad guy,” but I also feel like my love for him is fading, and I feel terrible about it. Any advice would be greatly appreciated.
