overreacting??

Me and my boyfriend of 3 and a half years have recently had a pregnancy scare and he took it well at first but as time went on and pregnancy became more realer he said things that made me look at him different. Such as him not wanting to have sex with me because it's "nasty". He then said he didn't mean that and meant it would be uncomfortable. That's after I cursed him out he said that and changed his words. I found it disrespectful honestly. This is your baby and for you to say you wouldn't want to be involved with me because I'm carrying your child made me hurt honestly. Am I over reacting ?
