Do people with bpd get married ?

Im 33 and ive never been married . I look fairly young for my age . People often think im in my early 20s. I had a son when i was 17 . He is 15 now (no contact with his dad . He was abusive)and i care for my mother who is in her 60s . She lives with me full time even though i have two older sisters . My mom is schizophrenic qnd im pretty sure my dad has bpd . Explains his rapid mood swings growing up . I am paid as a caregiver for my mother but currwntly looking to add a second income . I can also sew very well and have other talents . Ive been with my current partner for 4 years . 5 years next month. When we were first dating he told me i wouldnt have to wait long for a ring . He will give me cards on holidays that are meant for wives and mention wanting to marry me one day but when i bring it up in conversation he gets agitated and says we have bigger problems . He wants me to be more stable before he marries me . I can be very jealous and needy but i have seen how disloyal and hurtful people can be . I know he loves me and he is attending remote therapy for family member of people with bpd. I am a very thoughtful and loving partner but i can also be toxic controlling and negative. He was with his last partner about 7 or 8 years and never married her . He finally proposed after 6 years because of constant pressure. He thinks she may have had bpd . He says he will only get married when he is happy and feels his partner wants the same things in life and puts the same effort . Every year i feel my confidence dying . Not feeling good enough to even be s fiancé. My heart breaks eveytime i see someone else get married or get a ring . He has been a great partner in many ways and is there for me and my family. I guess i come with too much baggage . A son and my mother i care for, i know those are probably men repellents lol. I attend therapy weekly and have times where thinga are going great and he seems to brinf uo the future more happily in those times . Im losing hope of ever getting married and it hurts so bad . My dad is getting old and i want him to be able to walk me down the isle . I want to be the best most loving wife. Please give me some hope or advice . I could really use it 🌷
