Fairweather Friend 

Someone who poses as a friend when it suits them, but are shady or shonky at other times.

After Mat broke up with my friend, he would act extremely shady all the time, pretending to lose his phone, and pretending not to receive SMS's. At times there was even no toilet paper, or shit on the walls. He is a fairweather friend.
