It is good to be generous. It is good to give. But currently you may have heard situations were a guy trained his babe in school and she later left him for someone else. Does that mean you should not train the lady you love in school?
If you want to train any lady in school, do it this way.

(1) Let the lady love you so much more than you love her. If you are training a lady that loves you so much than you love her, you may not feel it if she leaves. Imagine dating a lady that you do not love so much; even if you are training her in school, when she leaves, you may not feel it much. You may even wish her well. You may even wish to marry someone else.

(2) Another way to train a lady in school is to train a lady you have no emotional feelings for. You can find a lady that is not from a well-to-do family and help her without strings attached.

(3) If you find a lady you loves so much, so desperate of, and that you cannot do without; please do not train her in school. You can assist her at some points, but do not take full responsibilities on her. If you are so desperately in love with her, and then you decide to train her, she may abandon you later, and this may cause you serious heartbreak.
