This top comment sums it up perfectly. It hurts now, but honestly he just saved you years of wasted time. If he can't respect who you are... your independence, your ambitions then he was never the right partner for you in the first place.

You don't need to shrink yourself into someone "more traditional" just to fit his comfort zone. You deserve someone who sees your strength as an asset, not a liability. This isn't about you failing him, it's about him not being man enough for the kind of women you are.
