Ah well - I'm afraid my EXH couldn't help you on that one
.
But I can tell you what stopped me from 'being weak'. It's something I have read somewhere by someone (sorry) and its something like:
When i doubted my love I stayed committed to my marriage
When I doubted my marriage I stayed committed to my vows
When I doubted my vows i stayed committed to my commitment.
Or some such thing but you get my drift. I did that, and it really helped me when it finally all fell apart, I knew I'd done everything I could but I couldn't fight the love he felt for someone else. I think that's where me and EXH differed.
