Somebody is claiming that my DP has cheated on me with them. Until this point I trusted him 100% but have a history of being cheated on in previous relationships.
I don't know what to think. My friends/family tell me to go with my gut instinct but this changes on almost an hourly basis. Part of me thinks that there's no way he'd do this to me, we've been very happy together and I know he adores me. He's also absolutely adamant that nothing has gone on and he's very believable. The other part of me thinks that there's no smoke without fire and that its unusual for people to make up these kind of lies. I don't know this woman so she has no reason to want to hurt me although she dated my DP a long time ago and according to DP was angry at him for breaking it off.
This is tearing me apart. I love DP but I can't stay in a trustless relationship. Anyone got any advice? Should I believe him or not?
