I wasn't sure what title to use so I aplogise if it is misleading or random 
Ok so I was with DH for 14 years. Lots of great times and 4 DC later we spilt.
Nobody else involved we co parent well and are still good friends we just lacked the love/attraction we once had and were more like friends, the decision to split took 2 years and was joint.
One of the things I liked and still like about exDH was that he is intelligent. We used to have great debates and conversations about everything from politics to womens rights. He was/ is always interested in what I had to say and commented often how I "got stuff" and explained my pov well.
He is educated to degree level and 9 yrs older than me while I left school at 16 with minimal barely scraped by gsce's.
He was never patronising he challenged me and made me think. I liked that.
Please bare with me all this is relevent I promise.
So I am now with DP.
We have been together 3 years.
He is lovely, supportive, kind, we laugh all the time and he makes me happy. He still gives me butterflies and I love him very much.
But.....he doesn't debate with me.
We do talk about topical stuff/things on the news but if I do not share his view he ends the conversation and even when I do share his view but I know/understand more about it he ends the discussion.
His level of education is the same as mine probably better actually.
It really frustrates me.
I find myself holding back when we chat about stuff just so the conversation doesnt end.
I miss the debate and passion of it.
I am in no way saying I am smarter than him but I do feel like I have to dumb the conversation down if I want it to last.
I know this seems like a stupid problem and he makes me happy in every other way but damn it I miss a good debate over a bottle of wine. I feel happier in my relationship but thicker if that makes sense?
Any advice welcome sorry it was longer than expected.
