Confusion Feeling :(

I feel really feel confusion now with my feelings because in one hand i love him but in other hands i worried that he was changes and i don't know maybe he is having affair there or whatever which i can't know about it.

Thats because some of my friends ask me did i really like stay with him, he is far away and i don't even know what he do in his country and it makes me keep thinking about that it makes me feel so stressful, i am feel anxiety now. oh my god please help me. :(
