Hi sunshine,
If I was your boyfriend, I would like to know about your FULL life as soon as possible.
Do not hide anything from him and definitely be totally honest with a visa application.
You have to run the risk of him being a little mad, but it should pass and he will respect you more if you confide in him.
The quicker you tell him, the less worried you will be and the faster you and your fiance can complete your visa and be together
