Name changed for obvious reasons 
Back story:
STBXH and I split up 18 months ago after a violent 6 year relationship. We share a 2.5yo DC, who he chooses to have little to do with. I've totally rebuilt my life, got my career back on track and am earning well, have a great circle of friends etc. Divorce is in the early stages. Day to day stresses of working a 60hr week parenting a toddler alone whilst a divorce is pending aside, I'm really happy.
My DPs have been visiting an East African country for 15 years + and bought a property out there 5 years ago. I've been out there with them (and STBXH) 6-7 times. They spend 5-6 months of the year out there and have a big social circle consisting of both locals and Europeans.
Around 6 years ago, my DF was introduced to a local professional in his hobby - let's call him A. A spent some time coaching my DF, they made good friends and meet up 2-3 times a week whilst he's out there plus chat on WhatsApp regularly when he's home. I have met A a couple of times at social events and we've always got on really well.
In October, news broke that A and his wife were divorcing. Sounded fairly acrimonious, lockdowns intensified issues they'd previously had. They remain on good terms and co parent their 3yo DS.
I can work fully remotely and last month, went out for 4 weeks with DD to stay with my DPs. I bumped into A whilst out running on my second day and we decided to run together each morning before work. I always thought he was attractive, and we always got on well, but the chemistry between us was like nothing I have experienced before. We both tried to ignore it - he was aware of what I'd experienced and that I didn't want anything with anyone. We ended up spending a good chunk of time together - running, he came for bbqs at ours, a handful of social events, a play date with the kids - and everyone commented on the chemistry between us.
3 days before I was due to leave, we were out running and he stopped and kissed me. I've never ever had "butterflies" before but it felt like a whole swarm of them in my stomach.
I came home and wrote it off as a bit of attention that I enjoyed post STBXH but the reality is, I cannot stop thinking about him. He has made it very clear he'd like more but he understands my situation and is happy to take things at my pace, if at all. He's spoken to my DP's and had the all clear from them, if I did want to press on.
I'm due to go back out early summer (was pre booked) and all I find myself doing is counting down the days until I can see him again.
In terms of age, I'm 29, he's 35. He is Muslim but not devout. Will fast for Ramadan but will also have a cheeky g&t. Appreciates that I'm agnostic (we've had lots of conversations about this). In terms of culture, is totally westernised, grew up with sisters and is a feminist. Earns well above his country's standards but little in UK money however is highly skilled and could earn good money whenever he went.
Considering his tie to my family, I don't believe for a second he is interested in money or a visa - he would have had plenty of opportunity for that with lots of others. In fact, this is something we have joked about.
My main concern is DD. Is it selfish for me to potentially pursue something like this?! We have ties to his country and he has a sister and a cousin close to where I live in the UK.
My dilemma is, could this possibly work/is this worth pursuing or do I write it off as a holiday romance?
