I am so sorry you are hurting bad. Break-ups can be devastating. Triggers will surround you for some time so you need to find ways to manage them when they do come. Everyone is different as to what works. For me I found mindfullness and acceptance (meditation) very helpful. To be able to accept the pain and not fight against it but instead let it flow through you until it passes - and it always does eventually pass. I went through an awful divorce so I totally understand the depth of pain you must be in. Hang in there and keep posting if it helps.
