Okay first of all sorry for making 2 posts in quick succession, though they are completely unrelated.

So I've known this girl for over 2 years. We met at Jury Service and I knew very quickly she had a crush on me, but I was currently deep in a relationship and never thought about cheating. I found her quite attractive though and kept in touch in a friendly way. Anyway, in December my 4 year relationship finished, so I thought I'd hit her up. We met up a few times (she'd drive to me with food, I'd drive to her with food etc) until one day I mentioned I had the house to myself and she essentially invited herself over. So she came over, we were chatting away, one thing led to another and I kissed her and fucked her all night. Since then we've met up a load of times and had sex, and I remember giving her the talk about how I'm not ready for a relationship etc and she said she was fine with that, and we continued fucking once a week or so. We spoke near on every day (I know, this is what caused this) until 2 weeks ago she started acting distant. I figured either she realised I'm a bit of a player (she's not the only girl I hit up) or she was falling for me. So today I text her with "hey, haven't spoke to you in a while. You all good?" and then received a wall of text about how she likes me more than a friend etc. So in a few hours, I'm going to pop round to her place (she's still with parents so probably just sit in my car) and have a chat with her. Now, I do kinda like this girl. She's fun to be around, sex is pretty good, and (sorry if this seems evil) I kinda have her wrapped around my little finger in regards to sex. If I want it I get it. I don't really want to give that up, and if I'm honest it probably would piss me off a little if I found her seeing someone else. I suppose anyone would say I should just get with her, but I really don't want to give up my single lifestyle of meeting and fucking ONSs and FWBs. I don't see us having a future together, she's certainly not Mrs Right.. Is it bad if I kinda use her as Mrs Right-Now?I'm still going to be playing the field as well. We can go out, go on holidays together and have fun as well as have sex but I couldn't imagine marrying this chick one day. Is that normal? To know that it's only gonna be short term? All of my previous relationships I've always seen a future in a girl and then after a few months/years realised they weren't the one and ended it. I suppose my moral compass is getting in the way a little bit here. Should I just man up and be the player I am?
