Hi soxcatch.
It is most natural not to trust anymore after having being betrayed in several ways.
But it is also important that you can find your trust back and be free to decide whether you want to give it to another person or not.

Not trusting others is the easy way: I've been betrayed, so I won't trust anymore. But it also the most painful, because not trusting means you never really give yourself out to the people you want in your life.

You should distinguish what was your responsibility and what was other people's responsibility for pas betrayals.

Once you do that (not so easy, maybe you can do it best thru some psychological help), you must simply accept that life is that way: each and everyone of us has the power to choose whether we want to stay true and honest or if we go for betrayal.

You keep clear from trusting thinking that you won't be hurt like you've been already hurt. But closing out true feelings makes you feel more alone than necessary.

Hope this helps you
