Single. I see people saying they'd just make her more independent but that's really screwed up to do. Either accept them as they are or move on. You shouldn't try to change people for your own desire. There's nothing wrong with being clingy by itself there's guys out there that want specifically that. It's just not for me but I won't try to change who they are because that's just narcissistic.
Honestly, the first one really isn't that bad. I don't understand why everyone is like 'oh she's smothering me!' She's showing you affection, attention, and that she cares about you. It's perfectly fine to me if the girl wishes to be over-affectionate and wants to tell me that all the time. I'll reciprocate the feelings because as a caring boyfriend it wouldn't bother me.
