Lou, get thee sen over lass! Life throws these little benders in occasionally deliberately to make you think and exercise your free choice instead of doing merely what's safe, learned behaviour.
Rise to the challenge. You know it's all going to work out don't you. Believe it's up to you to define your life and take control of your actuality. Make it happen the way you want it to.
You will deal with things because you have to. Do what's right for all of you. Take time out to just think objectively and avoid falling into that ever so easy trap of satisfying your egotistical desires i.e. soothing cravings - what'll make you feel better. Sometimes we're not supposed to feel better we're supposed to go through difficult and painful emotions otherwise how are we supposed to grow and learn more about our 'selves'.
You've already made a courageous decision, the hardest decision. That doesn't mean that it's easy from here in, committment raises questions. Don't avoid the questions, be honest with yourself and each other and you'll come out the other end in tact.
Its so exciting
Good luck hun!!
