Need some advice...

Courtney
My partner was over our mutual friends last night coz was watching football and having a few beers. He comes home at 5 am waking me up coz he's got the hump because our friend ( who I've known for a few years before I met partner) has told him how Before i met him I used to be after some other guy who we all know for months and months, ( I did have a crush on this guy about 3 years before even met partner, nothing happened apart from a kiss) 
I don't think he has any right to have the hump with me as I think he is overreacting, he said I should of told him about me 'chasing' this guy for ages - he already knows we kissed once but says he looks an idiot in front of our mate-
I went back to sleep and said would discuss when he woke up.. Am I in the wrong at all? 
I don't think It is important to bring up every person have had a crush on before we met 
I also think our mate is out of order for making a huge deal out of something that was so long ago and pointless!
Sorry for being so long! Any advice or comments will be appreciated
