Its amazing how you can love someone soo much for 20 yrs... Then after all their heartless behavior you go from begging for their love to confusion, acceptance to letting go and now im at the point where i rather him never contact me again. Ive changed his contact name to liar so when liar leaves me a voicemail my anxiety comes back. Ive blocked him but he can continue to leave voicemails... What did i ever see in him?
