I know many out there will say I should have just forced the marriage talk, but seriously who wants to force it!
Well, quite.
But I think that needs to be part of the awareness. That marriage is a commitment to a life partner, whereas having children is a commitment to children, NOT the person you are having them with.
Underlining that the bare minimum anybody deserves in a partner is somebody who enthusiastically wants to commit to you. And pointing out that having children before that commitment has been demonstrated may result in the realisation that you are tied forever more to somebody who did not reveal previously that they only had one and a half feet in the relationship with you from the onset.
The awareness needs to centre on a perfectly reasonable and healthy basis that people deserve partners that are willing to commit and anybody who is faced with a "reluctant to marry" partner needs to factor in the potential for a lack of commitment to surface at point when they are least equipped to deal with it.
Commitment is a contract entered into willingly by two people. I don't think marriage/civil partnership should be extended to "lived together for x amount of time". Because ethically I believe a contract is something one should actively choose to sign up for, rather than passively wander into.
Wandering into it could have the result that people are ending up in a contract they do not actively want because they did not have the means or the emotional/mental strength to leave within a time limit. Which doesn't sit right with me.
But above all, I'm sorry for the pain you have been going through. I discovered the reality of living together v marriage when my brother left my 8.5 months pregnant SIL, they also had a toddler. I was horrified when I realised just how exposed she was at her most vulnerable, when utterly devastated. And then he turned around and married somebody else within what felt like minutes of leaving her high and dry.
Seeing that is why I got married for the second time with a four year old in tow. It was act of self-protection, but, having held SIL as she worked through the impact of my brother's sudden change of heart about being married, for the first time I could see why my husband perceived my previous disinclination to marry again as a potentially half hearted form of commitment to him, and us.
