boyfriend troubles

au
So I caught my boyfriend talking to a bunch of other girls and lying about it.. finally, after several months of the heartache of this I broke up with him. We had our whole life planned out and I really thought his was the one.. after breaking up I found out a lot of stuff about him that people were keeping from me in hopes of not hurting me. I'm mad at him, sad, hurt but kind of happy living life for myself again, like does that make me a bad girlfriend? Everything had to be his way or no way before and I gave up my life for him. it's like a weight was lifted off my shoulders after we broke up, which is nice, but I miss having my everything.. any suggestions?
