hi is this the correct translation for

 I love my husband to be                            Nisanlimi cok seviyorum

"my husband to be"?

She means,the one who is going to be her husband

And she is talking to him ´adressing him´

My husband to be,i love you so much

Will it be,

Kocayým olan ?

sure that is not. by the way why not "fiance" if "going to be"?

I love my fiance: niþanlýmý seviyorum

I love my future husband: müstakbel eþimi (or müstakbel kocamý) seviyorum

Calling a man ´my husband to be´ is more special and endearment than calling him ´my fiance´even actually,they are both the same thing.
