My partner and I have been together for a couple of years now, and have been living together for just over a year. I will preface this by saying that DP's parents are lovely, and my DM is not as great - but there is also a huge wealth divide as I grew up poor working class with a single mum and DP grew up middle class with two high earning parents in a house they owned.
Since DP and I moved in together, DP's DM regularly offers us financial support. We don't need this as we both earn fairly well for our ages and yes we still need to save for some things but that's how it is when you're young isn't it? But DP's DM regularly offers to pay for things when we talk about things - for instance DP asked her DM where her DM got her mattress when she still lived at home as we're replacing our cheap one, and DM immediately offered to pay for it. Also, DP got a job in her field that pays a little less than the job she has now that isn't in their field, and DM offered to make up the difference until she's earning more. So it's not a fiver here or a fiver there - it's hundreds, and when we try to say no we're more than managing, don't worry, she sends it anyway. DP and I are talking a lot about our future and we would like to get married in a few years and DP has warned that her parents will want to contribute towards that as well as a house deposit. We are a lesbian couple, want children and will need to pay for sperm at the very least - DP says they will probably offer to pay for this too.
I understand that DP's parents just want the best for their daughter and they have the resources to do this and that's wonderful, but I can't help but feel really guilty. My DM will never, ever, ever be able to measure up to that. DP says it doesn't matter but I really like DP's parents and I don't want them to think I'm scrounging or using them for money when actually I couldn't feel more guilty. Do I just need to get over this feeling, or am I being terrible by not paying my way?
