About 6 months ago DH left his facebook messages open and I found messages from his ex. To put you in the picture she was cheating on her husband with DH (long before we met) so is not a very nice person. The messages were quite flirty but I didn't say anthing, just thought I would see how things panned out.
We were talking about it a couple of days ago and DH said he had not spoken to her for ages. He left his FB open again last night and there were two messages from him ending in kisses and the last one said "text soon".
AIBU to think there is more behind this than DH is willing to admit ? He has just been moved from working in our home town to working near her house and I am convinced paranoid that he is going to meet up with her. He knows I know he's been in touch and just laughs it off. I don't know what to do
