I really feel for you. Your husband is treating you like a child and that must be incredibly frustrating. There may be a more concrete psychological problem behind your husbands behaviour or perhaps he simply feels lonely? Does he have many friends and does he seem them much? I find people get possessive when they feel other areas of their life are out of control. Perhaps his job isn't going so well, maybe he has issues with his family or doesn't feel he can relate to yours and doesn't want to share? There could be numerous reasons for his behaviour of course but what have you done so far in expressing your unhappiness at the situation? Does he give you space to explain or does he just cut you off? Unfortunately situations like this can fester to the point where ultimatums are dished out and everyone ends up very unhappy and taking action they regret. I can only suggest you try and have a serious sit down and explain gently but firmly that you feel his behaviour is unwarranted and that you would like him to trust you because you give him no reason not too. Do you got out much with each other anymore? Again i keep thinking this is perhaps a loneliness issue - if you both find there's increasingly little time for each other through out the day can you maybe spend an hour together just making dinner or sitting and just being in each other's company. Sounds basic but sometimes being with someone isn't about activity it's about just being near them. I hope you feel you can elaborate a bit more, if not then i hope your situation improves through any suggestions mentioned here.
