Advice please... Jealous fella?

Am

Help!! I need someone to put my mind at rest. I've mentioned a similar issue before but I'm worried now....

I've been working a lot recently with other men as I'm involved with the army. There is a unwritten rule of extreme joke and mickey taking and a lot of rude jokes get told with soldiers, its all harmless and nothing is meant by it. Unless you have a military background its hard to understand.

My other half has been getting more and more stroppy about me being involved with other guys. It can't be avoided. I was invited to a formal dinner recently and my OH stopped me going by refusing to babysit etc. It felt like he was enjoying a power trip over me. Naturally I was extremely upset as I never go out or do anything for myself.

He's now reading my texts as I've had a few odd texts from the guys about work, and getting moody about the fact they have my number. I cant even mention these guys to him. His behaviour is just setting alarm bells off as my ex was controlling and abusive and I'm not prepared to live with that again. Do you think its just because he's being protective, a typical Muslim guy or jealous etc? I'm at a loss. He's the kindest guy but I've been single for 13 years prior to meeting him, mainly due to the ex putting me off men due to his nasty behaviour.

I've tried talking to him but I don't think he realises how much its upsetting me. Is it a religious thing? Any ideas how I address the issue?

Thank you ladies x
