I feel you man.
I was the exact opposite way. I was big into raving. Always gloving (led light show toy), kicked it with friends hardcore, dancing with new girls every night but never dated any.(never date a rave girl

) I was generally happy. Eat. Sleep Rave. Repeat. I had a job too and played video games.
Then with her came the bubble i stopped going out all the time. Saw my friends less and less until they all but disappeared. Couldn't rave anymore because she was insecure about me with other girls. Didnt glove as much too busy attending to her needs to the point that i got rusty...
Then we split the first time it took two months of NC to get my head back... then i started raving again met all kinds of new friends. Life was great and i was meditating, getting closer to my inner spirit, and even joined a sponsored team for gloving. Then came the recycle and since ive been such a seclude. With a constant mind on her, even my dreams. Im up till 5 am trying to fall asleep anymore.
Yes most people feel like ghosts to me anymore... because honestly i long for her company... anyone elses feels inadequate and hollow.
All distractions from what my heart longs for.
