Anxiety

Anyway we started dating and he was great until I realised he had anxiety issues. He's very conscious of upsetting others and making others angry.. He's been shut down by his parents a lot and the family favoured his younger brother more.. 

He's a very caring sensitive guy with soft heart and his family put him down for being "not strong enough". It seems to bring his work performance down quite a bit too because he gets affected when there's people conflict. He's very good with people usually because he is so pleasant to be around but he gets affected a lot inside when he is around strong and difficult personalities.  

The issue is not just about him. I love him and we are engaged and I knew about the challenges he's having .. But I know he can achieve many things with the right encouragement.. But I feel I am getting affected quite badly.. I am feeling anxious around him thinking that I shouldnt say or do anything to make him feel anxious.. 

We got engaged in July and are getting married next year March. But honestly i dont know what to do.. Sometimes i feel like I am making him more anxious. I have hot temper and Can be quite blunt. I showed a lot of my temper during the first couple of months of the relationship and I think he got quite stressed from that and he often appears worried about upsetting me. Even when we are with friends he is constantly glancing at me to see if I am okay. I feel it is overattentive but my friends joke and say "he cant keep his eyes off you!" But i know he's very weary of my feelings and my opinion  etc.. 

I honestly dont know how to approach .. He has very low image of himself because of the way his parents treated him as a child- always calling him an idiot, stupid etc..
