My boyfriend is 45, in the last 2 weeks he has bottled himself up. Says he has and issue he is dealing with that was harder to deal with than he thought it would be. He never had kids, says he loves me and that it has nothing to do with me or another woman. He has pulled away from me, doesn't text or call like he had been doing. He bought a motor cycle he wanted, his job runs him crazy.
I don't know whether it is a midlife transition, although it might be.
