I'll start by giving you a little bit of my background:
I've had my first gf when I was 17. Was not the best of relationships, I was young n dumb, cheated on her a few times (not something I'm proud of), one day I finally decided to act like a man and left her. I'm 21 by that time. After leaving her, I told myself I'd spend a good amount of time single to spend time with myself, meet different girls without starting a relationship. Well, 2 weeks later I meet a girl in a bar, we see each other again a few days later (just to have sex), but it didn't happen. We just talked, hung out and made out. She said she changed her mind and wouldn't have sex with me because she thought I wouldn't talk to her afterwards. She was probably right, so we hung out several times more, I got to know her, I got to know that she was dealing with pretty heavy stuff in her life, and we ended up being in a relationship for three years. This girl was different from the first, I did love her, but my desire for being alone and meeting more girls would always pop up, plus the fact that she was very attached to me and her problems were now my problems, which was a hard thing to deal with. I left her a little less than 3 weeks ago (been thinking on and off about it for more or less a year, it was a hard thing to do to break up with this girl, she was sweet).
Here I am, finally single at 24 y/o. I think that since I've been thinking about leaving my ex for a while, I had already done my grieving. I tell my friends at work, we go out and drink. We do it several nights and I make out with a girl at work. We end up having sex, both admitting to ourselves it's just sex. We've been seeing each other every day for about 2 weeks now, and recently she admitted she's been developing feelings for me... and I have too, unfortunately. I've never fell for a girl this fast in my life, we get along very very well, I've actually felt things with her I've never felt with any of my two ex's. On her side, she's been single for 4 years and she's ready to be in a relationship. We talked about it thoroughly, I told her it's not a good idea to go further and that we should stop seeing each other. It was sad times, she really seemed heartbroken and wrote me a nice message saying she understood and she supported my decision, and that she also thinks I should be taking time to discover and spend time with myself, even though she loves me (consider we've been working together for awhile, even though we were just strictly friends, she might have started developing a little something before I broke up with gf).
This is where we both fuck up. She asked if we could talk about it over a drink, I agreed and ended up sleeping at her place. It's just really difficult to leave each other alone. We're having a good time, we get along, and even though we're fully conscious that it might very well not work between us since I've still not had any time alone, we keep going. We go to gym together, she cooks me meals, sex is very good, we actually have good conversations... fuckin hell boys. I keep reminding her that one day I'll need that time, and if we don't stop now, it'll hurt a lot more later, but she still wants to see me.
One difficult thing that comes into play is that we work together. To not spend anymore time with her will already be difficult and if I decide to cut the string, I'll still be seeing her at work every week.
What do you make of this situation? What would you do? Need some advice boys
I just realized I got a little carried away and wrote an essay, here's tl;dr: been in 2 relationships for 7 years, needed time alone so i left gf, now i meet this new awesome girl, dunno wat do
