Is he not interested anymore?

My long distance boyfriend suddenly started ignoring me for a week. Everything was just fine before he started ignoring me. He did cheat on me in the past, so is he possibly cheating on me again, or has he lost interest? I am going nuts trying to figure it out. I may not speak to him again if he is cheating again.

Have you been attempting to make contact and he's just not responding? How long have you been dating? If my SO ignored me reaching out for a week with no prior warning, he would be single unless he had a very, very good excuse.

LDR is based on communication and trust. You have neither. Unless something very bad has happened (hospital etc) then he shouldn't just ignore you. That's not a relationship. Try to contact one more time and explain how it make a you feel. If he doesnt respond or have an appropriate response then move on.
