I feel really lost right now.
I have 1 dc with my dp and 1dc from a prior relationship.
Dp and i have been together 5 years. In that time we lost a baby, had our ds, had 2 break ups due to his mother being the most interfering evil witch known to man. He was also at fault not just her- endless false promises,lies, people pleasing.
Marriage was never a big deal to him but he knew it was very important to me and promised we would be engaged last year and make a fresh start. Again it was lies. (Not that i am sure it's something I still want anymore if I am honest)
Although he/we want us to try for another baby.
Can't comit to a bit of jewellery but can comit to a human 
We have moved past most if this now.
But we have had sex twice in the past 2 years.
He is the nicest person, has a kind heart, a little slefish at times but i am too. And we understand each other inside out.
We had a childless night last night and it was the strangest thing.
I just feel like our relationship solely revolves around the dc.
Every time we spend one on one time I end up sad and in tears.
I do suffer anxiety and depression.
Sometimes I think its me. Sometimes we are happy. But other times we just exist. Can there be just too much water under the bridge?
We are late 20s early 30s, life shouldn't be this stale should it?
Is it normal to feel like your relationship revolves around the dc?
