I've always been a bit introverted, but I still had a lot of friends before I was a JW. On becoming a JW I lost all my friends, and found no new ones in the cult. I eventually got married, but still had virtually no social life outside of that with my spouse. Over the next 16 years I lost many of the few social skills I had. When I left the cult my spouse deeply resented the few friends I made, especially those that were also ex-jws. She seemed to think that I should be content to be a recluse, since I was an ex-jw. She even insisted that I was "emotionally abusing her" because I developed friendships outside of the JWs. She seemed to think she was entitled to 100% of my attention and affection, while giving me only crumbs in return. I felt like a leper in my own home. Eventually I left.
Whether introverted or extroverted, all humans need social interaction to be mentally and emotionally healthy and happy. There's no getting around it. Even though I'm introverted by nature, I force myself to get out and socialize with people even when I'd much rather not, which is most of the time. That, more than anything else, is what gets me out of the depressed states I'm often in.
Hobbies, courses, and volunteer work are great ways to expand your social network. Invite your wife to join you in these. Even if she doesn't join you, she can never rightly say she's being excluded from your pursuits, and it reduces cause for suspicion.
