Attractiveness is only partly about looks. I know heavy people who are very confident and sexy and have no bother attracting people and slim people with cripplingly low self esteem who are perpetually and unwillingly single.
I've been both!
When I was younger I was petite, slim and blonde with big boobs but had fuck all confidence and so didn't have much luck with attracting people
After I split from ex I gained weight but also gained a lot of confidence once the divorce was dealt with as a result of other life changes and I was beating them off with a stick! Like even young very attractive people were coming onto me.
If you're too heavy for health that's a separate issue and you may want to lose weight for that reason. I'm planning to at the moment
But other than that you need to work on your confidence more than anything
My brother has a pal who ONLY likes plus size women, he's on his second marriage but we've known him since he was 10 and he has always gone for larger girls/ladies, he's very slim himself and sporty too so it's not a case of equal body types he is just very attracted to larger women. Has a huge crush on Alison Hammond for example.
Learn to love yourself
And consider what YOU want in a partner, are they good enough for YOU?
From your posts I'm assuming you're a single mum with youngish kids. That's immediately going to be an problem for one group of men
So true!
When I was OLD when it was a fairly new thing just after divorce I was early 30's with dd and a lot of the men just cba with someone with kids - their loss, plus they think that such a woman is going to want more kids and soon - an assumption that was wholly wrong in my case - again their loss
Do you mention you are a single mum on your profile?
And I agree don't rely solely on OLD
I met ex through friends, I met next boyfriend at uni, met 1st girlfriend through a hobby group...
I know it's hard at moment with COVID etc but generally speaking you need to get out and socialise
As you're heterosexual then you may need to make an effort to join groups and activities where there are more likely to be men your age - but that you also genuinely enjoy or think you MIGHT enjoy, I met my last gf at a group I tried but didn't particularly enjoy long term.
I've friends/family who've met their significant others at:
Church
Volunteer jobs
Hobby groups
Sports groups
Through work
Through their kids being friends at school
A few couples I know met via "mistakes"
One went to the wrong church for a wedding and the best man at the wrong wedding took a shine to her and sought her out
One was a wrong number phone call that ended up lasting 2 hours and resulted in their first date - they're now married baby on way in late summer
Be open to possibilities
Even at bus stops (I know that was a sarcastic post) but yes chat away to people at bus stops or train stations or in cafes. I've met and made good friends this way. One of my closest friends started out as someone helping me to navigate weird local bus system!
