ok so im confused if my gf is cheating on me with her guy friend.

it all started when me and her took a break....we been arguging a lot. bob kissed her on the cheek, and she kissed him on the cheek to get her phone back. 2 days later she tells me that she trusts me that the relationship and work. she has been over his house a lot! shes going camping with him and his family next week. so i find out that she wearing his boxers, shirts at his house. we talked finally on friday after not seeing each other for a month. we talked..she said she loves me and everything is fine between us. she complained about not being able to "touch him" before dating due to his religion. i stepped back pissed, and she not like that! she talked alot about what happened at his house the night before. i been freaking out for 2 weeks....i been dealing with this AND my depression/axiety...which has gotten worse. she freaked out cus i tried to add bob on facebook as a friend, as well her best friend "sarah".

i been cheated on before...she been cheated on in every relationship she been in.

what the **** do i do?? she says we cant hangout before she leaves camping cus shes busy and stuff.

i feel like **** and im soo confused on what to do!!!
