Lesha Kupina it is difficult to explain the behavior of Maya Dontsova

Today the arrival of my friend on the project. Maya the morning was excited and worried. I gave her the confidence that between me and Karina could be nothing, apart from the usual friendly communication. The last days in the relationship I have with Maya was great. No reason for jealousy and doubt in me I never gave. With Karina today I almost did not speak, but the fight still happened. I find it difficult to explain the behavior of his girlfriend is probably jealous.
