I was going to say similar to what Eric has said.
First and foremost, trust in Allah. The first 'relationship' you must have is with Him.
Nothing happens without His permission. Regardless it's what you hope for or don't hope for. Regardless you've worked hard on it, or you haven't.
So rely on Him for everything, all the time. Money, marriage, family, self, all matters.
If Allah decrees someone or something for you - whatever happens, how long it takes, whatever anyone does to get in between you and that person/thing - it will happen.
You need to put work into it, of course, for example if you want a trustworthy and reliable wife, put the work to be a trustworthy and reliable husband.
But if you don't have tawakkul in Him, in His plans for you, and that He intends nothing but good for you - you will not achieve that. because, how can you trust a creation, if you don't have trust in the Creator?
We humans are flawed. We are not all able, all competent, we succeed in some things and fail in other things. Allah is beyond all that.
We would like to have control over our lives, but we don't. We have 'some control', we can control our actions, our words - even that we fail sometimes and when we fail, we disappoint ourselves and / or others.
Only Allah has total control of everything. Make Him priority and He will not disappoint you.
