Can my partner do this? What are the consequences of his/her/my action?

You contributed 25 desktop computers while your partner contributed his management skills, as well as his expertise as a computer engineer, to put up an internet cafe that operates on weekdays from 10am to 6pm. Business was slow on the first few months and you realized that this is because serious computer users are either at school or at their workplaces during this time while gamers prefer evenings and weekends. You tried to discuss with your partner the possibility of extending your operating hours in the evening and opening your cafe on weekends but your partner refused saying that you should spend those times with your respective families. You were convinced that this was the right attitude so the following Saturday, you took your wife to Greenbelt for lunch after which you proceeded to Salcedo Market to look for artwork. You then came across a familiar face - your partner is also in the same market selling antique furniture and rare stamp collections.
