Not used to this affection

Covered in bruises. The nice kind but, I look at myself in the mirror and all I see is a tired, dull reflection looking back at me. My skin isn't as luminous as it used to be and my body aches. I'm happy, but, i'm letting myself go a bit. My routine has gone out of the window, i'm not eating very good food and i'm not sleeping enough. I'm broke. I can't seem to stop spending money. I'm not sure what's going on.
We are boyfriend and girlfriend though, so that's nice. It caught me off guard, my question to him but it went far more smoothly than when I once had this conversation before with Phil. 'So the other day I called you my boyfriend, how does this make you feel?' or something equally as lame. It was true, I did refer to him as my boyfriend to a work colleague but didn't think about it much as he wasn't there to observe it. I felt silly afterwards, realising how I was putting myself out there once again, I admitted to feeling like a teenager again, a little awkward, a little daft to ask. He smiled and held me close, he beamed at me happily. We are on the same page. We talked, shared stories at how we'd felt anxieties in the past about 'not knowing' with other people, the games people play and how we're both not into them. I like that. 'Got myself a girlfriend' he joked as he hugged me, it was so sweet. I suppose I feel a little relief but then I was expecting it a bit, the amount of time we spend together, the plans we make, how he is around me. I don't believe he's been messaging anyone else or wants to date anyone else, but then he has so much potential to move about with his work, there's a risk that he might move. He mentioned how if he hadn't have met me he would probably contemplate moving back to Ireland for the generous funding of his book. I told him not to make any judgement calls based on me, though it did make me feel happy to hear.

He uses 'my love' in messages and says 'I really like you' when we're together. I suppose i'm just not used to being with someone who's so affectionate and open about how they feel.
