My bf is great - loving, thoughtful, loyal, etc etc - my soulmate and The One in my life. We have lived together for 3.5 years but were friends at work a few years before that.

I have no basis for my suspicions yet i get all stressed when he gets sms messages, puts his phone on silent - all logically explained when i ask about it. We try to be open and honest - he knows i have trust issues - and our motto is: if in doubt, ask!

Obviously i have a longer story, this is the shorter version to get started in here. Last night i questioned him about fb issues, his phone etc and he just sighed and said 'i just wonder if you will always be this suspicious of me'. That shocked me and i want to move away from this untrusting behaviour.

I am diagnosed bipolar, on lithium which helps me lead a normal life, not too many moods swings - i often wonder if i would have been a bit moody anyway, even if i wasn't bipolar.

I love him, he's great - oh, he is 14 years younger than me, i forgot to say that! I know i have some jealousy issues about younger women and i am probably scared of losing him. We have a good thing and i know i have to alter my behaviour if i want to keep this relationship good.

Any ideas or advice?
