Need advice

My friend and i had feelings for each for about a year now.we decided to do istikhara but after that i felt a change in him he gets irritated easily he once told me he can’t tell me about everything thing in his life and when ever we fight fight instead of resolving he acts very weirdly and now during ramadan he is saying that he feels uneasy talking and has religious guilt and keeps saying that he is seeing signs

What should i do
