I think, one month into the relationship and feeling the way you do about him, you need to take that leap of faith and disclose your past.

If you don't, you will fall even deeper in love and it will eat away at you; if you don't tell him AND if he chooses to leave you over it, then your heart will be further damaged.

If he cannot handle it and leaves you anyway...then he wasn't worth your time and you will know that and will recover a little faster and a little easier.

Either way it's going to be tough.....But I really don't think you should wait...

Hugs.
