Panic attacks is not something one can control. But I’d be concerned if my boyfriend still lived with parents (after being 5 years in a relationship? He must be an adult not a teen?), does not work (why doesn’t he work?) and we still do not formal commitment (why does he need that many years to commit?) and now he is panicking about pregnancy on top of it.

Honestly if a man is not ready to be a father he should refrain from intimacy because that’s how one becomes a father. Sure there is birth control but clearly it was either not used by you both or if used it failed. If he enjoys intimacy, he better be prepared for a consequence of it. It’s health education 101. Does he not know about birds and bees?
