Sweetie, he's shown you so many times already he has no interest in having any kind of relationship with you, he is interested in sex only. At least he's been honest - it's actually easier this way because you don't have to second guess yourself and his motives.
You're moving on by grieving and letting him go. Nothing can heal broken heart but time - but you have to allow this time by staying NC or LC if there is no other choice.
Good luck, your xAP doesn't really seem worthy of much suffering.
Love and hugs,
