Hi dreaming715,

You are right in identifying about unrealistic expectations.

@anita has already explained everything rightly, so keeping it simple…..

True love is not about “wanting” the other person to behave in a particular way, but it is about “allowing” the other person to just BE.

But at the same time, keep your senses open and just don’t “give-in” everything for the sake of the relationship.
If you are looking for a long term relationship then bring that balance between what is fine with you and what is not.
Meaning – does he intends to first get married or wait for some more time before going ahead with a good night kiss? Gradually figure this out. If you find out that he is

NOT

the kind of person who will love you and be interested in a good night kiss even after marriage, then that is the time for you to make a decision whether to go ahead and make this person a partner for life or not.

Similarly figure out about other things in the relationship and work on striking the balance.

Take care.
