I have carefully read your question and description, and my views are as follows:

First of all, as his girlfriend, you should know something about the type of work he is engaged in, the intensity of work, whether he travels frequently, etc. Otherwise, you will be kept in the dark and cheated by him.

If your boyfriend really needs to work overtime or go on a business trip, you should be considerate of him. After all, he worked so hard to give you a clear and bright future.

If your boyfriend is a playboy, you should be on your guard, but you can't argue with him rashly. I believe that paper can't contain fire, and the truth will come out one day. Arguing and theorizing with him now will only bring you endless trouble. Besides, if you are wrong about him, it will seriously affect your feelings. Therefore, it is best to wait and see.

These are my suggestions for reference only. I hope my answer can help you and make you satisfied.
