Hello Wanderer!
Your parents love you and want what’s best for you. I’m sure their concern comes from the fact that you’ve just overcome cancer and surgery….they want you to regain your equilibrium before you make a major life decision. My heart says “Fly! Do whatever you want!”….but realistically there are other things to consider: Will your relationship with your parents be destroyed if you follow your heart? Would that be OK with you? If you wait the 6 months they are asking for, will they support your decision to leave your marriage to travel and find yourself? Are you afraid to wait those 6 months because you think you’ll lose your gumption or just because you are impatient to go? I’m just hesitant to tell you to screw your folks and do what you want if they are important to you. They might know you well and have a valid argument!
As far as your husband deciding to be nice and helpful after you’ve said you want to leave…..maybe he has realized that he just may lose you and wants to make changes. Only you know that. If so, can your marriage be fixed? Would he be ok with you doing some solo travel if you came back to him after….maybe a separation?
If you are truly unhappy with your life and circumstances (I’ve had a small cancer so know a bit about how it makes you think) then I say go with your heart and make those life changes! You need to live an authentic life, for sure, and never stay where you are unhappy just to make other people happy. I’m just suggesting, as devil’s advocate, a few questions you might not have asked yourself. My 2¢.
Best of luck to you and good vibes!
