Is it time to get a divorce ?

Okay so, lately I’ve been finding myself feeling stuck. I’d rather spend time with myself then with my partner. I fantasize a lot about what it would be like to be single. I know that sounds horrible.. but I’ve also felt like me & her moved too fast. Me & her argue a lot now, and we haven’t actually spent a thanksgiving together because both years we ended up fighting & doing our own thing. I just feel like there’s more to myself than I know & I kinda feel like our marriage is holding me back from completely being myself. I’m gonna get TMI, but I’m a super sexual person, & she isn’t so I find myself not satisfied & feeling like I have to hide that side of me. Idk if any of this is making sense.. but I’m just kinda lost & I don’t understand why I’m feeling all of these feelings. I love her so much but I just feel like maybe we aren’t meant to be..I just don’t feel in love anymore...
