my boyfriend hasn't acted like he did when we met and got together, like actions and words showing he liked me and my body since a month after we found out we were pregnant so at 12 weeks that all stopped... well around 25 weeks we stopped having sex cause he didn't want to... that made it even harder and I thought he was cheating or jacking off or just really didn't like me anymore... well now that I'm back in PA at my parents on maternity leave we've been setting for the past 2 days and sending naked pictures to each other and he's been saying all the right things again! it's amazing and I missed this and I can't wait to get back to Ohio with my son and see him for the first time in a month and have sex with him for the first time in months! I'm not sure I remember how to do oral or sex to him lol 😁 it's been that long.
