Relationship Advice Please šŸ˜©

Long story short, I have been with the father of my unborn (13weeks preg) child for about 10 1/2 months. We arenā€™t official and he has commitment issues. I was his official girlfriend for about two months before he broke up with me saying he was too stressed with life events (parents messy divorce , school, work, etc.) and hasnā€™t asked me to be his girlfriend again since. I donā€™t understand the big deal and try to see his point of view but just canā€™t. Im loyal to him and he says heā€™s loyal to me so whatā€™s the big deal to be his official girlfriend? weā€™re having a BABY together ? we spent most days and nights with eachother. he says heā€™s ā€œscaredā€ of the official commitment and loves how things are now. we act like a couple and bring eachother around our families, plan to live together once baby is born. im not sure what to do at this point seeing as I love him and want to be with him but i just want the title so badly I donā€™t understand why I donā€™t have it yet since we act like weā€™re a couple ?! Iā€™m trying to be patient because other than not having the official girlfriend title he takes great care of me . P LS give me some advice on how to deal with this?!

p.s no, itā€™s not possible he cheats, iā€™m with him 24/7, see his texts that come in, and trust him when it comes to that aspect.
