DP and I have a mutual friend who we usually see every other day, He lives locally and usually comes over dinner or a catch up, We've known him for over 5 years now and for a period of time he lived with us before we had DD. He's been like an uncle to now 3yr old DD.
About 2 months ago he started a new relationship, he came over and asked us for advice on dates etc. We were genuinely excited for him as he's quite often "friend-zoned" and it was lovely to see him so happy. I started to get concerned that we hadn't herd from him after a week of the relationship starting, DP assured me he was probably "in the throws of love" and so would be a little preoccupied to say the least. I agreed.
After 2 weeks, I went to his workplace as I was in town anyway to see how he was. He said he was fine, had been staying at his new girlfriends alot. Over lunch I asked about her, we joked about falling too fast. Then he dropped a bombshell, he told me they'd had a pregnancy scare! Having seen DP and I go through the struggles of an unplanned pregnancy, I thought he would have known better but I just said to him that he needs to be more careful, and possibly move more slowly as something like pregnancy this early in a relationship could have the potential to be a disaster. He agreed, I told him if he needed someone to talk to he knows either me or DP would be happy to lend an ear.
When I got home, I started to worry he'd told me the GF was alot older than he is (he's 26 she's 35) and had previously been engaged but it had fallen apart a year ago because her fiancee hadn't wanted kids. I didn't want to judge her before getting to know her so just put it down to over thinking things (a habit of mine).
I've now invited them round for dinner a total of 6 times. 3 of those times they told me they were coming, I bought and prepared food and then each time I get a call from my friend telling me "sorry GF is ill, we cant come", or "GF has to work late we cant come". The other 3 times they've just outright said no they cant make it, fair enough.
So, now 2 months into their relationship DP has even started to worry. We made the decision to contact our friends house mate to see what was going on. His housemate informed us the last time he actually saw our friend was a month ago when he came to collect more clothes but he still pays his rent on time. We asked if he'd said anything and well this is the bit that worried us. The housemate had said that his GF insisted on driving him to and from work even though they work an hour away from each other and that when he'd said he was going to go home as he had to open up his store the next day she'd out right said no and that she'd get up at 3am in order to drive him to work just so he'd stay with her.
Sorry this has been so long but I'm genuinely worried that my friend has got himself into a situation that he cant get out of. I don't know whether it would be unreasonable to talk to him or to just let nature take its course and just be there whatever the outcome. The other thing is am I just completely over-thinking this? Any advice would be great.
