would it kill him to ask someone about the dogs?
no, but again, he is taking you at your word. you said move out, he did. you said no thanks to support for the dogs, he said ok. he is leaving you alone. do you have any idea what ONE contact from him would do to you?? considering your current fragile state, it would just throw you into a serious tailspin.
he's doing you a favor. it's over. relationships END all the time. yes breakups are painful. but they are a part of the whole package called life. OUR ability to let go is what we should focus on. to fully accept life on life's terms and that we don't get to KEEP everything and everyone that comes thru our lives.
now is the time to invest in good self care. to start filling yourself with good stuff, NEW stuff. at 30 you have so much life yet to live, explore, investigate. make 30 your turning point. be fierce.
