Dp and I moved with ds to new area, 4hrs away from my family and friends 2.5 yrs ago. We separated almost two yrs ago and ds and I moved to own place, close to where dp lives, within walking distance. Dp came round every night for bedtime and spent all weekends together...we were working towards reconciling..until new girl (17) started at his works, and they had a fling, no sex involved (allegedly) although she stayed at his place a few times. Back and forth between her and I, eventually chose me. Still works with her. One yr on, he's getting distant, they had works night out last night, which I was told could not go to as 'no-one takes partners', 'it would be awkward' etc. So he arrives at mine today much earlier than usual, ho hum. Do the usual,mundane shopping etc., This evening after a drink discloses that she, having been sick through drinking things she couldn't handle, because was bought from a 'kitty' and then carried on drinking, might well be his ideal woman. I ask why he is still here then, he replies 'dunno', ask if he is happy, says yes, but maybe he could be happier, he doesn't know. Ask if he is saying these things so I will finish it, he says maybe...just discovered he has me on limited profile on fb (suddenly, he doesn't think I would know)and am breaking my heart as unsure what to do now. Feel like walking away for gd, I have an ok life here, ds is v settled, but feels like he wants me to do this to absolve him of any guilt. Maybe am being paranoid, but he said ' you know what they say about things people say when they are drunk, they speak the truth'. Am in bits, was so ill last time, barely held it together and my ds missed his daddy so. Ways? Any advice please, major alarm bells ringing
