know where near to the same extent as the op, but, a similar thing happened to me two years ago. I’d been with a girl five years, happy, never argued just as you two. Then, after a drunken argument, all my fault I’ll admit it I was a dick, she came out with she wasn’t happy and that she didn’t want to be together anymore. Like you the world fell out from underneath me. I was happy, I loved her and more to the point I loved our life.
This all came out on the Saturday night, but wasn’t definite. By Monday I pushed for an answer, she couldn’t give one. That was enough for me. She left that day saying she was staying at a mates for a few days. That night I went into our bedroom after having a shower and she’d left a partly packed bag, an over night bag if you like. I was having friends on at me saying “their must be someone else” etc so I looked in the bag. There was a flat let prospectus from two weeks previous, so she was well down the line by the time we’d had the drunken argument that Saturday night. So I guess my point is this, by the time she’d said something she was already well down the line both emotionally and practically.
I feel for you lad, I really do. But all the old cliche’s probably apply. It probably is for the best, it will get worse then it’ll get better.
I never really went on here when I was going through my break up, but I can see why some do. I’ll leave this post saying, use your friends, don’t hold things in. I have a top best mate who I couldn’t have been without during my break up, in fact i’e a couple of mates that really kept me on the straight and narrow and gave me crucial advice and support when I needed it most.
