Tim, hi

, you're here so that means you have a lot of resources, hope you've used them. One of those resources is about the grief cycle, one stage of which is 'denial'. That's where you are now brother

she's kissing another woman and having 'impure' thoughts, maybe she's not a lesbian, maybe she's bisexual
