Well, it sounds like you’re going after women out if your league because you think they’re attractive and that’s a valid choice. But it is a choice you’re making. It sounds like you could have intimacy if you lowered your standards or increased you attractiveness (gym etc). Or you could abandon dating to not have to face rejections.

So I think the key to avoid bitterness is to reevaluate if the choice you are making still works for you if it brings up bitterness. Then you can either stay with your choice or switch, if you don’t think any other option brings less negative feelings.

And if you choose the best option for you, there’s no need for bitterness.
