Husband giving me the ick

My husband and I are hard core in the roommate phase lately. Like i kinda feel like we just tolerate each other half the time. We haven't even been married for 3 years, and romance is long dead. Lately he's been really whiny. He's either aggressivelu complaining about something and insulting everyone involved or he's just straight up whining. It's really gross and giving me a huge ick. And I feel like I'm losing my ability to empathize with him. It's just so hard to care sometimes. This marriage is making me a worse person and I hate it.
