I’m team son.
He’s completely allowed to feel the way he felt when she asked him if he wanted to marry her.
He felt the gf putting pressure on him and he sounds like he did not want to feel under pressure.
If the genders were reversed no-one would support a man applying pressure to a woman to get married.
The many posters supporting team gf because she knows what she wants are prime hypocrites.
If the gf wanted marriage she could have:
a) started the conversation a second and a third time.
b) proposed an engagement to him
c) proposed marriage to him.
It sounds like the gf stewed on one conversation and without a series of conversations or distress flares she went ahead and ended everything giving him very little notice.
That’s not marriage and partnership material behaviour. That’s not kindness in action.
And that certainly was not love in action.
The now ex-gf had only her needs in mind and clearly didn’t care about his feelings/wants and needs.
The conversation could have been the starting point of a beautiful dialogue of understanding each other’s needs, triggers, desires and vulnerabilities.
But no, the gf had to pull the trigger.
There’s another man somewhere, and she’s interested, I guarantee it.
The 30 year old son is well away from such petulant and childish behaviour.
