Lots of women find themselves in this situation.
Early on, they were laid back about marriage and didn’t mind too much either way. Perhaps they then decided they would like it, but by then they had bought a house together and even had a child. Marriage had never been part of the deal and so it felt wrong to push it too hard. But lots of women do really want it and as time goes in feel more and more disappointed when their partner won’t really engage in talking about it.
On one level, if it wasn’t part of the arrangement or plan for the future early on, why should a man suddenly find he has to do it when he didn’t want to, the goal posts have been changed. On the other hand, if someone isn’t that bothered and not actively opposed to marriage (the position of many) why wouldn’t they agree for the person they love who they know really wants it.
Essentially though, I think it’s actually really important for women to clarify their own position in this earlier on. If women want marriage, they should say so even if there is no timescale to it. They should voice this desire for the future, before moving in or having children. Certainly once children are there, it’s much harder to leave someone who doesn’t have the same life goals. Drifting into living together and especially having children without having talked and found agreed life goals (which include attitudes to marriage) just opens the way to one or both people being disappointed.
No one is saying anyone has to agree to marry at an early stage or to say the relationship will end in marriage. It’s about talking about that being how you see your life path. Talking about how you see your life path in terms of things like career, marriage, children is really important. It doesn’t mean the marriage and children will be with the current partner. But if you are both diametrically opposed on a key issue, it can flag that considering whether to continue or not in the relationship is a good idea. Just not talking about it (and lots of people really struggle to communicate, especially on these issues that might provoke disagreement) is burying your head inn the sand and building up trouble for later.
So to Op, I’d say it’s a shame it’s got to 18 years and this wasn’t sorted out much sooner. It’s something those in the first year or two of a relationship might consider carefully or even those just starting out and considering g moving in together. But for now, I would say to partner that you want to have a definitive talk about this issue. Even if he is huffy about it, say you want to. Set a time and date to have a really good, thorough talk, rather than one where a few things are said on the back of another conversation but the conversation isn’t fully had because someone goes off part way through. Think carefully about all the things you want to say about it as an issue and recognise you can’t keep having the big conversation. And consider carefully what your response is going to be if he categorically says he won’t marry you. You can either accept it and live with it (you need to decide if you can manage this) or nor remain with him. Do t make idle threats of leaving him if you don’t mean to.
Sadly lots of women are in this position. They don’t want to leave and they won’t leave because there are children, they do love the man and they can’t imagine a different life....but they just aren’t as happy as they could be. And that’s a great shame, because they are missing out on a key element if life that is important to them. It can be like the sadness people feel who would love to have children and can’t or don’t.
