Long story short, yesterday (when i was at school) my ex boyfriend call me and ask me to give him my phone number. I rejected but i told him that I unblock him from Instagram. I felt bad for my boyfriend because i feel like i m cheating on him so i decided to tell my ex to just chat me from messenger. (My boyfriend has my messenger account password. That day he say that he hasn't went into my account yet.) Cause my ex boyfriend said he had something to ask me about his school work. Around 6 pm in my country, I waited for my boyfriend of course to chat with him. But he didn't came online so my ex boyfriend came to talk to me and ask me if i have boyfriend or not. I asked him why and he answered "I just miss you" Then i went to tuition, and came back. I went to my room around 10:30 pm and text my boyfriend first. And later just reply ex boyfriend message. When my boyfriend reply my message, I called him. And explain everything to him and told him that he could log into my account and read the messages. Then he stop talking to me that night and went on call with other girl. I got so confused. Now, i m talking with my boyfriend. He is explain me everything that since after his gym, he was thinking of ways not to fell asleep at night when i talk with him. I hurt him right? Today at evening he told 2 new girls that he love them. And they start to talk about love in front of me (he also give me his messenger password so i basically can see what he is talking about) it hurt me really badly.
please can you give me an advice? What should I do now? I am stuck.
