Back story is as follows:
I'm a man. Been with my girlfriend for about 3 years. A bit of a rocky relationship due to distance, external factors etc but ultimately we were a very good, happy, solid couple who were quite clearly perfectly suited to each other.
Anyway, about 5 weeks ago she ended things. It was because I changed a weekend plan (not for the first time) at the last minute. I fully accept responsibility for it - I was wrong. I'd done it before, and clearly hadn't learned my lesson. I have no argument against it.
She ended things because she felt like I excluded her from my life. Time with my daughter. Time with my friends. She was always happy to include me in hers, but I found it difficult to include her in mine. For many reasons, but mainly because of the way I split with my ex I was hoping for a totally fresh start and wanted to leave my old life behind (aside from my daughter of course). I've tried everything to convince her that I really want to settle down with her. Have invited her to move in with me. Promised to make a concerted effort to show her that she is inclusive in all aspects of my life. But to no avail.
As well as being partners, we were the very best of friends. In both of our minds, at the very least we want to retain the special friendship we always had - we share so many interests and hobbies and that's part of what brought us so close to each other. I'd do anything I could to stay a part of her life, and she would do the same.
The problem is, I'm so in love with her and so heartbroken that we are no longer together, I'm finding it next to impossible to move on. I of course want her to be happy, but selfishly I want her to be happy with me and I can't help feeling that way. I'm so desperate to move on and yet stay friends with her, but it breaks my heart every day not to be able to message her or call her in the same way that we used to.
I'm just looking for some general advice as to how I can make it less painful to move on. For both of us. Is it even possible to salvage a friendship when you are so in love with somebody? I dread to think how it will be when she meets somebody else, but for the time being we still have a few pre-arranged plans for things to do together over the coming months and in order to ensure we don't hurt each other, we have agreed not to date anyone else until at least we've been away in September.
General advice really needed on how to "man up". Or really, how to just feel ok about everything. Thank you!
