No sex!

Ladies please give me advice!! I been in my relationship for two years and my boyfriend say he's stressed out and it's spilling over in the bedroom we haven't had sex in almost 3 months! I love him but this is driving me crazy I have talk to him about it but he says I'm only thinking about myself and I'm just a adding more stress to him bcuz that's all I think about is SEX! Anyone else had this problem if so how did u deal with it and did you look to someone else for ur needs😔!
