Is it guilty or cheat?

I was talking to 2 people at the same time ( only chatting or over phone) bcz I thought about my boyfriend that he used to talk with someone else bcz I found his ex’s number and some other number that are not usual and same time he was not talking to me normal and ignoring me again n again.. so how it happeneds.. but after a few months he found out.. after that I don’t know what to do I started telling lie again n again but to save our relationship and he confronted me and I accepted all my mistakes but he is taking my lies wrong and now he is thinking I was always a liar with him.. so it hurts me.. I was always loyal for him in past years but he is not understanding me.. and now I am suffering from depression and not able to do anything even if for my career n for my health.. I tell him that it will never happened again but he is not believing on me.. and hurting me a lot..
