Update: After too many ignored calls and messages, on Sunday I had no choice but to talk to him. He decided to go to my house knowing that he had a big chance of me not wanting to see him. My mom convinced me of talking to him.
When we talked, he swore for his grandma that he didn't cheat on me. His grandma is sacred for him, so that kind of made me believe him. I don't know how but we just ended up getting together. I say I don't know how because I don't believe his story. He was giving me eye contact and talking to me very serious but I just don't believe him.
He told me that the woman that he talked to at 2:30 am on Friday was about a work related meeting that they were going to have on Monday. She called him to ask him at what time was the meeting going to be and since the phone call got cut he had to call her back. That is how he explained to me the incoming and outgoing call, which I don't believe.
Another thing that makes the whole situation kind of fishy is that the woman told him that she called me many, many times to clear things up. She told him that I would say that it was the wrong number and hang up on her. He said that he made sure that she was calling the right number and that he was sure she had called. Weird thing is that I had no missed calls and I have not talked to her since what happened, I only got one message from her a week after the incident. Why would a serious older woman lie to him about that????
He also just told me that he has to work on Saturday. He has not worked on a Saturday for the longest time. I think he is lying and has to make it up to the "woman" for texting me and making me believe that there is nothing going on between them.
I totally can't believe a word he says. PLEEEEEESE HELP!!!!!!!!!!!!!!!!!!!!!
