My ex = short. My NEW boyfriend = TALL!!! What's the ex thinking?

My ex boyfriend is short, my new boyfriend is SOOO TALL. There is about a foot of difference! The other day my ex saw me and my current GIANT boyfriend at the grocery store, we exchanged awkward smiles. Do you think the ex was jealous because my new boyfriend could pretty much play for the knicks? My ex was alone, and I tried not to be TOO cuddly with my boyfriend because I didn't want to seem like I was "rubbing it in." The breakup was my ex's fault, and also, would a guy care at all after seeing their ex girlfriend with a much more height -endowed (and cuter) new man?
