Not from your provider. I have a subscription to call Europe that only costs me £13 for 3 months. So it well worth to have a try. I'm 100% there with you regarding him coming to see kids, that's why I decided to take the to see him. Seeing him coming into what was our house was hurting like hell and it was mostly preventing me from healing!!
I'm not 100% happy but I longer wake up in the morning feeling sorry for myself or thinking of him. Like you my H is done and enjoying his life with OW. I think they are well match as both don't have values regarding wedding vows, and now it's find by me. At least I can hold my head high that I didn't disrespect my H by having an A. If he is happy, then I wish him all the best. Everyone deserves to be happy LBS as well as WAH/ WH. If it's not with me a least I'd have had some years of happiness and two beautiful kids out of it.
I'm starting to behave as if and most importantly I believe that I'll be fine in the end.
Hang in there IP and listen to your inner voice. Take care and loads of hugs xxxx
