Hi @JKCR2017
First of all, I think its great that you have a partner that you can potentially marry while you also have grandparents that are alive. My grandparents have all passed and it really hurt me that my grandmother was not here to see me marry my husband last summer.
I realise that in today's society, most people view a relationship, kids and a house as the same as marriage, without actually having to get married. I have family and friends who fall into that category and thats fine for them. Your grandparents are probably more traditional (like me) and understand that. marriage is a greater commitment between two people and for some (also like me) between that couple and God.
From what you said it sounds like you would like to get married. Taking away the money aspect first of all, you get to have the same last name as your child. Also, being married connects your family so much closer and your children will grow up to learn, understand and respect what marriage involves. You may love your partner now and be committed to him but there is something different about actually being married to that person.
On another note, I wanted the big, fancy wedding and I got it. It was not easy, we saved, took on part-time jobs, bank loans, credit cards and we pulled off the big day. As much as I do not regret my wedding day and the way it was, looking back I kind of realise that if we had done something smaller then I would just be as happy today but with less debt.
There are a few ways you can have a wedding on a budget but for it to still look nice and fancy and also a few things you can do before your engaged. The first point (something I wanted to do but never did) is that you can actually start saving now for the wedding even though weddings are not on the table and your not engaged. Most venues require a big deposit of £500 to £1000 so even £50 a month is something to get you started which will surprise your partner when he finally pops the question.
As for budget weddings: you can have a week day wedding (for one venue it was £6000 on a Wednesday and £9000 on a Saturday for a 120 people guest list). The other factors is how many people you invite. Most places charge by the person for a three course meal and drinks package. Say a venue is £50 per person then you x that by your numbers of people. If you both have large families then its difficult to narrow down the list but you can have a small reception and ceremony with like 30 to 50 people and then invite 100 people more in the evening to see your first dance.
You should look for a venue that includes the wedding cake also. If your not religious (or would find a minister/priest) who would do the wedding in a hotel then a ceremony and reception in the same venue would save on cars (that cost me £800). As for decoration, you could potentially do it all yourself or shop around for decoration wedding companies and you can spend as little or as much as you like on that. You can buy a dress off the peg and ask friends and family to donate to your photographer etc instead of a formal wedding present.
These are some suggestions but the point is you can do it if you work out a plan. I see you say you need a new kitchen and you also have kids (I don't have kids yet) so that makes budgeting and planning harder but you can also plan a wedding and book over 2/3 years. I saw make up artists opening their books for 2021!! So seriously it can be done.
I think the first thing though is waiting on your man to propose. Drop a few hints here and there but generally do not push him as he can change his mind afterwards. You have a child together and thats already a big commitment, either way he is in your life forever but if your truly meant to get married it will happen one day. You just have to be prayerful that it will happen before your grandparents leave this earth.
I would discuss it with him more and then leave him to think. I do hope my suggestions and advice finds you well and I wish you the best of luck and happiness in 2019.
