Hello, I'm frightened to ask for your opinions but I need impartial advice rather that from family and friends and a pair of fresh eyes.
When I my partner and I first met he mentioned he was best friends with his ex for years and very close to her family. I thought that was quite sweet and accepted this. As our relationship progressed he would do strange things like take a photo of our ice-creams in front of me and send it straight to her (all innocent it seemed). Out relationship has been pretty much a rollercoaster and often when we've had an argument he would go to have a few drinks with her brothers.
However, the odd time when he was very angry he would make a comment about her or at least compare us. This started to happen more and more when we would bicker. Anyway fast forward a few months and her mother messaged me after and argument on fb and deleted it again. I asked him and he said she had told her mother we had argued and she wanted to confront me. I started to become suspicious from here.
Months later I explained that I was now very uncomfortable with his constant exchanging of messages and I think it should be limited out of respect for me. Now, 3 weeks ago he told me after a few drinks that she had been working at the same place as him but a different department and that's when alarm bells went off so I decided to go on his phone.
There are 1000s of messages between them, both name calling me, both flirting (some of his are just vile) and ones saying they love each other. They both have played hard to get with each other from the messages and ive noticed soon as we was getting on he would start to ignore her or minimise what he had said to her. She would then message and say that she was going to message me as he was ignoring her and he would panick.
Once confronted, he childishly explained all of it was in response to us arguing and that they're just friends and they both don't see each other like that and haven't for years. In all honestly I am gutted and really upset but dont know whether to believe him. I dont think anything physical occurred between them. Is there any possibility of getting through this?
