I need to vent for a minute. I've been with my fiancé now for almost 3 years and I love him dearly. I'm due any day now but being induced on the 9th if our son doesn't arrive before then. My fiancé has been everything but financially supportive throughout my whole pregnancy. He helps around the house and all that. What is worrying me, which is probably just my hormones talking is he works as a car salesman. So he's around the cute sales girls and receptionists at work more than he's around me... We had a fall back in October I found out he had nudes of all his exes and friends on his email and hidden in his computer which lead me to distance myself from him and lose trust. That being said, I feel like something weird is going on. And I'm not sure how to bring it to his attention. He's always talking about his coworkers. There was one I had a huge issue with named Nicole. She has a son, she's single and very attractive and he'd never shut up about her until I told him to. Now, yesterday he brings up this receptionist I think her name is Danielle. About how she's married, 22 with a 4 year old daughter (so obviously talked to her enough to get all this info) and how she thinks it would be awesome if our son dated her daughter and they were best friends... Like no. First off, ain't gonna happen. Secondly, he had to call the store yesterday on his day off to find out what time he worked today and she answered and transferred him over and before she did that, he goes "thanks Danielle" and she giggled. The fuck. And recently, he doesn't kiss me the way he used to. Now it's a quick I gotta go I'm in a rush kiss. No matter what time it is. It's weird. So idk if I'm just over reacting or how I should go about talking to him... Because we're both very open with each other. I'm just worried. My body isn't the same as it was before I got pregnant. I don't dress up anymore because im too lazy and tired. So maybe he's just not feeling it anymore? Idk. Any advise would be welcomed lol :)
