The chicks always ruin everything

Yesterday I had the mood on the low point. The reason is certainly well known and already discussed here, nevertheless I would like to put him to the discussion: one of my dearest long-term friends and of all those who taught me to drive especially curves after the driver’s license, gets driving restrictions from his girlfriend, and also a ban is in the room. First came the son, then my friend built her a house and now she complains, he should the moto I think that’s very selfish and calculating. I mean, she met and accepted him as a motorcyclist and now that she tied him to herself, she wants to take away everything, even his favorite hobby. I don’t understand that. Is the motorcyclist the egoist, if he pursues a quite dangerous hobby, or is it the “suddenly” clinging partner, and how would you resolve the situation if you were affected?
