You already know from her phone records that this guy isn't just a friend. Leave her and find someone more deserving of your love and commitment.
Put yourself in her shoes for a second. What would compel you to offer massages and say I love you and hugs and frigging kisses, and text everyday??? Not sodding friendship, not even shared interests. She's not using massage as a symbol for golf sessions.
Either way, if she's refusing to give up that particular friend, I'd already be packing my bags, or telling her to pack hers. She would at least be making a compromise if there wasn't something going on, and you know fine well there's something going on. It's there in her phone records. Imagine what actually might be happening that has no paper trail?!?!?!
If he wasn't interested, her texts wouldn't have gotten this far, and she wouldn't be texting him so often, every single day!!!!
