Could “end up” also follwed by past participle?

For example,

  1. I ended up satisfied. (shoud say “being satisfied”?)
  2. They ended up stuck there. (should say “being stuck”?)

Those are all OK, with or without ‘being’.

Thank you!
The other day, I asked if I could say “before delivered” instead of “before being delivered”,
then answer was NO.
Is that because “before” is preposition while “end up” is “transitive phrasal verb”?
If so, I can understand.

One more question.
Can I use any pp after “end up”?
Or just pp that has been adjectivenized?

like,

  1. She didn’t have many friends at first but ended up loved by everybody.
  2. I loved her very much but ended up rejected very easily.

Is that because “before” is preposition while “end up” is “transitive phrasal verb”?
If so, I can understand.-- That’s right.

Can I use any pp after “end up”?-- With ‘being’, I think you can.
Or just pp that has been adjectivized?-- Without ‘being’, I think that’s right.

But the degree of adjectivization may be difficult to determine:

3. She didn’t have many friends at first but ended up loved by everybody.-- OK
4. I loved her very much but ended up being rejected very easily.– OK

Thank you for correcting my example.
Oh, yeah! It seems very difficult for me to determine! Xp
