Ladies, was i a bad bf ?

I have this ex gf who for some reason really really hates, and to be honest, as much as i would like to think that i was a great bf, i can honestly say that i made a lot of mistakes while i was with her. First of, i disrespected her by insulting her faith. I had never met anyone who genuinely believed that the Genesis story really happened, and i went to all catholic schools, but she was evangelical christian, and i said something along the lines that you had to have a really low iq to take the bible that literally. Now.. I am a scientist, and i do believe that you have the right to believe what ever you want to believe, but there are somethings that you should be able to understand are made to impress and should not be taken literally. This was a big issue between us and it made it difficult to do things that we both enjoyed... i liked science museums, she .. well.. didint.... even the observatory was a problem.....because everything that there was an insult to her faith...!!!! Apparently she really holds this against me... and as much as i understand that people have a right to believe what ever they want, i am a scientist. I know what i know... not what some book says... There were also other issues, in that i wound up lieing to her a lot because was so insecure. I honestly felt like i wasnt not allowed to talk to any other women. She would check my facebook and myspace pages, and anyone girl that commented on my page.. she wanted to know who she was .. where we met.... yada yada yada..... I actually even lost contact with one of my best friends, who is a girl, and yes.. i did have a huge thing for her in the past....but she never felt the same way so i had let her go..... and i was honest about this with her in the begining....!!!! but that didint help.. .. I also had a tutoring job with to college girls, and everytime i would tell her were i was i would get the 3rd degree and that "I KNOW YOUR CHEATING ON ME " attitiude..... so i would simply lie to avoid the fight!!! ... was i a bad bf for doing these things... I mean .. i loved her very much, and i still do .. even though she wound up leaving me for someone else about a 8 months ago .. with out telling me... she just kind of walked away from us... and now she is engaged..... so .. was i a bad bf?
