I feel I am in way over my head and I don’t know what to do 😭😭😭😭

I love this man with all my heart but I feel our entire relationship is dictated by his 3 year old son and his ex. They do not have a good relationship and fight a lot and I have never been around children before and I feel so overwhelmed when we have him overnight. (His actually a very well behaved sweet little boy, I just feel so out of place)

I so desperately want my own family one day in fact I’ve wanted children for years. (I’m 30) But I was hoping to build my own relationships and family, not take on someone else’s where everything I do will always be dictated by others.

I don’t know what to do, everything else about this man is perfect. Things are still new (it’s only been 3 months) will adapting to a step parent get easier or am I better to step out now and save more heartache down the track? I’m just feeling so overwhelmed 😭 x
