You feeling inferior is within you and nothing really to do with IVF. Conceiving children via IVF or having children via any other methods or not having them at all is not shameful or embarrassing or in any way makes one inferior. You feeling that it’s shameful is within you and something for you to work on. Its not shameful for others

Neither Bob nor his wife nor any other person on this planet think anything bad about IVF. Only you do. No one cares if someone has low sperm count or low egg count. Or anything else whatsoever

I really think you’d benefit from therapy.

Your inferiority complex is taking over your life. You couldn’t sleep for 3 nights thinking somebody is superior to you. Either because of their height or how they conceive children. That’s just not a reality. Your inferiority isn’t real but it’s within you so you perceive it as real.

It’s not your wife’s fault you feel inferior. You said you aren’t blaming anyone yet you blame her for you feeling inferior to other people. Her sharing something completely innocent and extremely common isn’t causing you to feel inferior. It’s within you. But it doesn’t have to be this way

I highly recommend therapy for you
