Just a tip, don't try to talking to W's friends again about any suspicions you have or even ask them generally what is wrong. They are HER friends and will run to her and you will end up looking bad. If she is close enough to them to tell them what is wrong then they are unlikely to be there for you - they are there for her and will see you as the person she has painted you to be - not as you are.
