Such complications normally are seen when couples live apart. If you can somehow live with him, this will be great, however, in current situation, if you see change in him for good, you must bear patience with him and give him a chance. Make dua to Allah and seek His help and guidance.

My husband and I have been married for 7 years now. We used to live together. After 5 years he got a job transfer, so we started living separatly. I am staying with his family. He usually comes after 8 to 10 months. When he came for the 1st time everything was ok and he went back again. When he came for the 2nd time, from no where I saw some text with a christian woman him having an affair. I asked for divorce but he refused and he said there is nothing going on now. I stayed because of my mother-in-law who at the same time is my grandmother, me and my husband we are related. Now he is back there again and I can see some change in him but am still worried maybe he is still cheating me. Please advise me how to control myself.
