Is it bad to admit your feelings? For example, telling someone that you think your falling for them.

Or

That you've been thinking about them a lot.

Some of you will probably think it will sound super beta and needy.

But regarding a serious relationship/establishing a serious relationship after attraction/comfort stage. Shouldn't it be allowed to express affection?

Can't really be cocky/funny/douchey ALL THE TIME, amirite?
