'Your wretched loneliness doesn't fool me'

Thinking about relationships or even attempting to embark on one is causing me some confusion. Confusion that is rising from do I or don't I? As I've covered before in previous posts, I still miss my wife. My ex-wife. Earlier this week when I passed a garden centre and saw an advert for coal and logs it immediately transported me back to a time when we had our own open fire and would buy logs or home make our own fire-lighter bricks and the ache inside deep inside was strong. It reverberated around like a yearning. A yearning for my old life with her.
With all of that can I really expect to start anew with someone else, with all of that still swirling around inside, ready to unleash on me whenever something of her pops up to remind me?
It feels like it's lying there dormant just waiting to unleash memories and feelings as soon as something triggers it. Much like certain blogs or websites use Trigger Warnings to warn individuals of certain elements contained within I think I should have the same scattered throughout my life to warn me of potential hazards.
'Trigger Warning: Passing through that area we used to both drive through together'
'Trigger Warning: Playing a song you both discovered and liked'
'Trigger Warning: Feeling stressed waiting for that hug she used to give you'
The whole thing is tiring but I don't know how to curb it all. 
Perhaps I can't and time is the only way. I try to remind myself of what she did and that sometimes helps but the feelings still linger.
One day soon she will be nothing more than a memory.
One day.
