"when we argue, he doesn't talk to me until i go and kiss him."
I feel a bit sick
.
I totally agree with what everyone else is saying. All that stuff at the beginning of your relationship, the flowers - that was the act, designed to reel you in. This new guy who's mean to you - that's the real one.
Everything he told you is him projecting his own behaviours onto you. So when he doesn't trust you, it's because he knows he himself cannot be trusted; and he cannot believe that anyone else, including you, can be trusted - because he, the untrustworthy one, well, he's normal, right? (No, he isn't, but that's how he sees the world. Totally screwed up.)
"In the first year he wanted to spend all the time with me, always with me"
So if he was spending all his time with you - this would lead to you never having time to spend with other people, right? Friends? Family? How much have you been able to keep in contact with your friends and your family since you have been with him? It's a very usual tactic of abusive partners to isolate their victim from their friends and family. Makes them easier to control if they have nobody else to talk to, no 'sounding boards' to mention the abusive partner's behaviour to, to talk it through with. Make no mistake - your partner is abusive.
"so i tried to change, not to argue so often, to discuss more, not to be so needy"
And so become a shadow of your former self
.
"i don't know what to say..if it's my fault"
NO! No, no and no! It is not your fault. Abusive people are con artists - they know how to mislead us normal people, and by the time we realise what we are up against, we are weakened by their insidious abuse. You are not at fault here, not in any way, any shape, any form. IT IS ALL HIM.
I know your heart is broken, the future you had mapped out for yourself has just been snatched away - but I'm afraid that future was never going to happen. All he would have given you is more of the same, meaner and meaner, until you were a broken empty shell.
Take the strength you still have and end this relationship. You sad 'in your own house' - legally, whose house? Owned or rented? His, yours, both? If yours and only yours, send him packing. Make sure you go over the house with a fine tooth comb, tech can be very small and I would expect to find more cameras. If shared, sell up/end lease. If his, move out ASAP.
I'm so sorry OP, but the best that can be said is that you found out before you married him.
