Sorry for spitting hairs here, but I once had a jealousy problem that I went to see a shrink about. I got over it, but he pointed out the definition of jealousy:
1. Fearful or wary of being supplanted; apprehensive of losing affection or position.
So THAT doesn't apply here.....
2 a.
Resentful or bitter in rivalry;
envious: jealous of the success of others. b. Inclined to suspect rivalry.
a Seems to apply....
3. Having to do with or arising from feelings of envy, apprehension, or bitterness: jealous thoughts.
Usage of the word...not really applicable.
4. Vigilant in guarding something: We are jealous of our good name.
Don't think that is what we're talking about....
5. Intolerant of disloyalty or infidelity; autocratic: a jealous God.
Also not what we're talking about.
Now if we go to Envy to cover definition 2a, we get:
a. A feeling of discontent
and resentment aroused by and in conjunction with desire for the possessions or qualities of another
So it looks like number 2 definition is most applicable to this case, which means if you say you are jealous, then you are probably feeling a bit of resentment and calling it jealousy.
This is why I worded the question as resentment in stead of jealousy. Believe me, I'd much rather use the word jealousy myself. I'd feel better about it. But in being honest with myself, it is simple resentment.
