Search Results: i want to dump my boyfriend

Unfortunately, I live with my boyfriend but he stays in another city to earn money.
We split house bills in the house and only goes home one to two weeks per month.
Four months ago, I saw a girl who keeps calling him every 30 minutes but he won't take it.
Until such time, I get his phone and he named it "Dianne Manila GF" and her text "Babe, how are you doing?"I woke him up and get mad. He denied it and said. I don't like her she is just my friend."

There was a time where I ask him that I want to follow him in the City and just apply work there. He said a BIG NO, we can't be together anyway. We have to rent. I keep calling him every night but I wonder why he can't even answer my calls. I get annoyed and put him into test thinking he maybe living with a girl.

At 2AM , I keep calling him and say if you won't pick up my phone I will think that you are really living with a girl there and you are cheating on me!!! He was terrified and keeps canceling my call. Until after 15 minutes, he answers my call and said What do you want? We keep talking for how many minutes. And suddenly the day after, someone chats me on Facebook and her name is "Dianne", she ask if I am his girlfriend who called him at 2 AM? She said she saw my name while she is playing a game on his phone. She also said HE also stays with her. She knows at first that he has a girlfriend, but later on, my boyfriend said we already break up. She said, she just wants to know the Truth. I said YES, I AM HIS GIRLFRIEND. , She said, they met last July in Tinder and said I don't want to break any relationship. We are just friends. I call immediately my boyfriend and this girl suddenly block me on facebook.

WTF. should I believe him or dump hi, m? Is there an INFIDELITY GOING ON?
