Confused?!?

Well I just told my boyfriend about lying to him about being on birth control a few weeks ago, hence now I am almost 5 months pregnant, and he took the news ok, but as i pretty much expected he was still really angry about it. But for the most part since i told him he’s gotten over it. It bothers me too, because i feel like my baby was concieved because of a lie??

And my boyfriend has promised he’ll be there no matter what and he assures me of that. But sometimes when I say "I love you" he asks "Do you really love me or just the idea of me??" and of course I tell him I really do love him. It doesnt start an argument but i think its kind of a hurtful question for him to ask but in a way i do understand it.
