So after thinking everything over and over I really think tomorrow is my deadline!

I think its about time for me to get my life finally straight and stop living a miserable depressing life! But I know its going to be hard but I know its going to be worth it in the end!
If my fiancé does not give me an answer as to if she will officially move back in with me tomorrow im going to just give up and officially end our relationship and complete shut off from her! I'm 24 and I want to be happy! i was always happy and every one saw me happy! I made everyone else happy but now im just not the same no more! we been engage for 1 1/2 and in a relationship for 7 years! we both are 24 and we have a daughter together and we been separated for 3 months! I truly believe 3 months is more than enough time to get your mind straight and realize if she still loves me the same or not! especially since we have a daughter together that's 9 months! This is going to be really hard for me but im tired of being sad! I just really don't get her! she tells me I love you every day and when we do see each other we always give each other a kiss before I leave! I have a good relationship with my daughter in which I keep her every other day because I love my daughter so much!
But in all honesty i'm tired of being alone! I really am. I hate coming home to an empty apartment in which only I live in and always think in my mind will she be walking through that door today!

I hate being sad. and I think its time to officially just end our relationship officially ( we are broken up but talk everyday and see each other about everyday) I guess the main reason is I put my hopes too high every time we text and talk and see each other.
Do you think im doing the right thing?
