uncertainty

Life is really uncertain at the moment, there are so many things to consider and it is hard to know if any decision made would be the appropriate one. I need to retrain in order to get a job that pays above the minimum wage as my previous career is now well and truly over, and although people say it like it's easy, it's hard when you have no income to pay for it, so if I scrape the money together somehow, will I get work to pay it back when retraining is finished?
Friends are another strange thing. A friend told me that another 'friend' was spreading malicious gossip about me to all and sundry, yet the two in question meet up regularly? Are they both responsible? Does the one who meets me just want more gossip? My instincts used to be pretty good and I would know who to avoid, but after years of being bullied and manipulated I don't trust my instincts so I only see my family. After all, families might be horrible sometimes but at least we all look out for each other and we can predict when things will go wrong most of the time, as well as enjoying nice things together.
Partners are the most perplexing though, my husband will help anybody but his family. It isn't just me, he won't help our child, his parents, his sibling and certainly not any of his in laws, yet he will go to the ends of the Earth to help his friends, usually female, calling different countries to get information for them, and the ones he 'helps' are usually those going through a bad relationship. I try to be objective the my instincts are really screaming about this one, especially as he is there to 'help' her enjoy a day out, and he needs to destress from work too so this, to them is a good arrangement. She probably thinks we are separated, he is open about her thinking that if he is I won't think anything of it but it bothers me tht I may be wrong. It's not that I think he's having sex with her, that bothers me, but not as much as the fact that he is intimate with her, he is there for her when she is upset, he shares her happy times and doesn't expect her to pay for everything.
I think I have convinced myself of what I shoudl do about one of the situations I find myself in.
