I went through this exact thing living with my significant other. Girl, leave while it is early. Thats the one thing I regret not doing. Leaving early on. He is battling his own issues. You dont deserve any confusion or inconsistency when it comes to a relationship/love. A partner should be able to communicate with you. Especially while living together. Maybe he needs the opportunity to live on his own and be in his own space if he hasnt had it before. This is going to be stressful on YOUR mental, while he goes on abt his day(s). Sending love❤️
