I lost my virginity, but...

Me and my boyfriend have been in a relationship for 14 months and it's long distance. The last time he was with me, we gave up out virginities to each other and he left a couple of weeks after that and he avoids talking to me now. After all of it happened, I felt sad, lonely and that he didn't really care for me as much as he used to. He says he loves me, but I really don't believe him because he's lied to me before. All of this hurts so much and I'm so confused. Pleas help?
