How do I start...

SuperMoniMonk

I feel like I need express exactly how I feel for I'm fearful I'm may not make the right decision.
I met a wonderful man over 18 months ago , we are engaged . It all started as an online relationship. He is a smart, kind , professional man,He is a widow who's wife happened to be my brother's in law cousin. We began chatting and got a long quiet well. He has two daughter 16 & 11 and he is very devoted to them. I like that about him.
His wife died of cancer 5 years ago . To make the story short, we decided to make things official and I moved to this country in central america so we could get married at the end of January. I live with him and his girls . Although he is a good man ..there are things that bug me ever since my lifestyle took such a drastic change.
I have always been very independent and now I find myself depending on him for everything , even to go down the street.
I know it's a phase but when I explain to him that I get bored being at home all day ..he shuts down and doesn't say much .
We were meant to go out for dinner but when he came home he said he rather go to lunch tommorow ..If I didn't mind.
I couldn't help ..I was so dissapointed . He doesn't seem to understand that I feel like I'm going nutz just being in this house all day.
His girls usually go over to there grandmother's ..I go visit everynow and then , I'm still adjusting to how life is over here since it's not a very safe country ..I can't just drive anywhere ..or go for a work. Last time I got on a bus I was robbed ! I just express to him that I need to get out ...go to the grocery store , the mall..whatever he can just drop me off. as I explain that to him ..he just hugged me tight and didn't say nothing , he then rolled over and felt asleep!!! ok so he is 10 years older than me..and since he works he is tired and falls asleep easily while I'm right awake with my fustrations.! my mind begins to wonder if this guy is just too boring for me . Will that ever change? but then again I'm happy that he is not a heavy drinker or a party animal. During the time that we were talking online ..we talked about the wedding and how it would be ..also about the rings ..and I;m so dissapointed that he still has not gotten me an engagement ring . I was hoping he would surprise me with it ..but now he says he was us to go pick them out . Once marry there is more to do...
I'm an Australian Citizen and once we get married we will begin the whole immigration process to move over there probably in 12 months time,, this means visas for him and his two girls . I can't help feeling pressure of getting used to living with a man who has children ..one of them a teenager..also thinking about the culture shock they will go thorough once we get there ...I;m going through it here and i know it sucks!
I don't know if I'm mostly unhappy because I'm not able to live my life as I want while living in this country..or if it's just that we can't understand each other .
at times I feel like quitting everything and just keep living my single life as always...but that would be the easy way out .
part of me likes family life...part of me misses the independent ..not having to worry about no one but me ..( sounds selfish)
there ara times that I;m happy to be with them ...the girls are sweet , and he tries to comfort me but it;s not working .
I came to guess bedroom to type this bc he felt asleep..how boring...:(

I don't know if im just exaggerating and this will pass ..for I know he does try..or if it;s just a phase of adjustment. For I know I would regret just leaving him. am I just mourning my care free life that I used to have...is this just a cross roads..o should I just run and not look back..uugghh!
