no sex over 6 months!

So me and my partner have only had sex about 2/3 times since being pregnant!
It's hard at the moment as we are living at my parents but they have been away and out for some nights so we could of done it then. 
We have also just been away to Turkey and only had sex once out of the whole holiday! 
He advised he finds it weird having sex due to the baby! But my 😻 anit pregnant it's in my tummy! He said the thought makes him feel strange! 
If I'm honest I think he has / is having Alex with other people or sex services as I found some emails on his phone saying hard dick and asking if they had any time for him! I'm in such a situation as he never admits it and says it's something else or he does not know how these sent emails got there!
I'm a fucking MUG!!!!!!!!!!
