So my FH and I got engaged in Oct and set the wedding for the end of sept.

We thought that sea trials for his new sub would be over by then since commissioning is in oct, but now it has been pushed back a month and is expected to continue getting pushed. So we have had to move the wedding date to the beginning of May, up by 4 months.
Not to mention that since we were engaged so late in the year, we waited on booking anything just to make it through the holidays, with as little stress as possible. Not knowing the boat was gonna end up behind schedule. Im at a loss, because FH isn't gonna be able to get time off during sea trials and his MCPO is of no help. His CHOP is trying to get schedule info for him, but the command has a clique issue among the officers, and he is not as in the know as he is supposed to be. The CHOP's wife(who was really helpful with advice new yrs eve) suggested I speak with the Ombudsmen, who can get me the schedule info since she is supposed to be having monthly meetings with the CO.
Neither one of us want a court house wedding, and we are even postponing a honeymoon. Also, waiting until after the sea trials are over is not an option cuz the boat is changing home port when the trials are done.
How else can we get info w/o getting FH in trouble? He is one of 2 senior enlisted PO's in his division w/ 2 E1's and as we get closer to trials, the less time he will have. We hired a wedding planner to help, but im worried that this change in wedding dating, which cuts four months of planning off, will be too much to handle and we wont have the wedding we hoped for. I dont even have a dress yet. The BP is small, just MOH and BestMan. And we are cutting corners every where we can in order to keep costs down. We are even going with an all-inclusive package offered from the venue we have chosen, that will save us $$, but doesnt gives us as many options we would like to have. We are paying for this ourselves, and his dad said he would contribute. My family is poor, due to bad economy in our area and my father isnt the type to help. (he gave my sister $100 for her wedding and said that was more than our older sibling got at her wedding, like he was doing her a favor).
Im also afraid I wont get to experience a lot of things because of the lack of money within the family. I know bridal parties, and engagement parties and the like are all gifts and i am not entitled to have any of it done for me. But its a dream every girl dreams of. I have appreciated all the help my poor mom and MOH(twin sister) can give me. I cant really expect for much else from anyone else, since the family dynamics among the extended family is strained (for other reasons.) Im just so worried that things aren't gonna work out.
