If there isn't passion anymore, is it worth pursuing?

I question that to myself every morning now. I barely see you and even if you're here, your mind isn't here. I really want to support you through this but recently I feel exhausted from it all. The rare few hours become shorter and shorter everyday and now all we talk about is university related.

Where did the passion go? The chemistry?  The butterflies in my stomach?

I don't know what happened but I feel like we're an old married couple. You come home to a cooked meal with me and then we sleep. We used to go to sleep at crazy hours early in the morning. There used to be so much banter and laughter. We used to be attracted to each other. Now even when is dress up for you, it seems like nothing to you.

I miss you so much and I don't want to be that spoilt brat who demands everything to be done her way. But I can't help but wanting more. I know you can't give me more which is why I feel even worse.

I love you. I honestly do. But I'm finding it harder and harder each day to give you my love when you give back 30%. I feel like I'm giving more effort into this and I can't deal with it. I know I sound like a bitch right now but I miss those times you would surprise me with a cute text or you would pay attention to me. All the little things you used to do. Of course I understand you can't give it to me now... but when will I feel how I used to? It's not fair that I have a boyfriend yet still not feel as if I do. You're too tired to care for me anymore and it makes me sad I can't help you at all. I can't even say I love you anymore.....
