boyfriend problems

Rehka
So I have been in love with this guy for over a year now. We have been off and on but, to my knowledge, have not been with anybody but each other. We lost our virginity to each other new years going into 2016. We have been going out since July and this past week I found out that he has been lying to me about the stupidest things. Like he tell me all this stuff and I don't even know what to believe anymore. I don't want to be with someone who is so comfortable lying to me, about anything. I find it so disrespectful. It just sucks to think that I have put in so much effort with this guy to try to make things work and I just ended up getting used and taken advantage of, again. I guess I'm not really looking for advice just venting.. I don't know where to go from here.
