could it be said that it was your anxiety and non-acceptance of the situation that caused the split? and now you are realising what you have given up? The reason you may only be remembering the good things could show you how ‘un-real’ anxiety actually is in the reality of it all.

you have time to yourself now and can work on re-setting yourself and looking at things from a far. Once settled can you try again and accept the situation? which will probably release some anxiety. Is being with him in a less than perfect way better than not being with him at all? Is giving it another 6 months to be in this situation again the worst thing that could happen?

Did the relationship not match your perception’s of what made you feel secure and therefore you were reacting on the back of your vulnerabilities?

You sound like you may have acted in a way that I am currently battling with, The relationship not having all that I perceive to need to make me feel secure! and I today I have decided it is living with my vulnerability that is the issue here. Accepting that and deciding to go with it and bear all actually feels liberating. Just some ‘food for thought’ here.
