It is not unreasonable to expect honesty in a relationship. It is also reasonable to expect that if we spill our guts to someone we don't know very well, some will take advantage of that vulnerability and abuse it. Or use it to their advantage thinking we are just (too) trusting so they can do whatever they want. Which sounds like the case here. Even with some backpeddling
I would encourage you to take stock of what you are looking for in a relationship, must-haves. And do NOT compromise on those.
It is clear that you would like to be with someone that is trustworthy yet you are sending the message that you are willing to bend.
That is not healthy for you. You send a message that you do not have boundaries and that is a recipe for a big mess and lots of (unnecessary) drama.
Please be good to yourself and respect yourself. It is ok to have boundaries. There are plenty of wonderful, decent people out there.
