I have dealt with this in the past and I asked the Lord what a good solution would be. I feel He said something like this: However we perceive the Lord is relating to us, that is generally how we will relate with our lover, or all people for that matter. So think about it.. Perhaps to have a happy balance we could see the way God is and then we will be like Him more and more. Think about how Christ loves us alot, enters into a close intimate relationship with us and fully accepts us based on His performance, not ours.
and then this is a nice verse.
He has shown you, O mortal, what is good.
And what does the Lord require of you?
To act justly and to love mercy
and to walk humbly[
a] with your God.
obviously some expectations are good but it probably best to discuss these sorts of things best you can before you even begin "dating" persay.. then you will not be so "interupted" down the road by unexpected expectations. its simple.. as your getting to know someone you may be interested in ask them what there expectations are. you may not be able to define all of them and a lot of time people change and grow in what there expectations are

but you can probably get a pretty good idea right off the bat whats going on
be blessed yall! peace be upon you in Jesus!
