I visited my 23 yr old Son over the weekend. I live 2.5hrs from him. Parked on his driveway and we headed straight out to lunch, shops etc. At the end of my visit I said I will use your loo before I leave and he said I couldn’t. Apparently his GF was in his home and she wasn’t ready to meet me due to anxiety. I said I only need a wee, I actually thought he was joking but he wasn’t. I left close to tears that he would do this to me. So I just left. I found a garden centre 25min into my journey home to stop off at. I’m still in disbelief that he treated me this way. I’m really hurt by this. I do have some medical issues at times which mean sometimes I really do need the loo urgently and he knows this. On this occasion it wasn’t to urgent but he didn’t know that. I don’t know how to move forward from this. Am I being unreasonable to feel so upset by this?
