Leanne ~ my husband was offered a great paying job rebuilding East Timor he was supposed to be gone for 6 months he was there 3 weeks he just couldn't do it his kids are his life and couldn't cope a minute longer i think you will find the right answer when you take every thing into account including emotions. JMO single mums and mums living without their partners are just so strong and my hat off to them and only you know whether you can do it
